Description
본 발명은 레이더 시스템에 관한 것으로, 특히 레이더 송수신 튜브의 시험 및 측정에 관한 것이다.TECHNICAL FIELD The present invention relates to radar systems, and more particularly to testing and measuring radar transmit and receive tubes.
일반적으로 레이더에서는 수신 및 송신을 하나의 안테나로 하고 있는데, 송신 출력과 수신 입력의 에너지 차가 크므로 송신출력으로 수신기를 태워 못쓰게할 염려가 있다. 따라서 이를 방지하기 위하여 안테나와 송수신기 사이에 송수신튜브를 사용한다.In general, a radar uses a single antenna for receiving and transmitting. Since the energy difference between the transmitting output and the receiving input is large, there is a concern that the receiver cannot be burned by the transmitting output. Therefore, in order to prevent this, a transmission tube is used between the antenna and the transceiver.
송수신 튜브는 송신에너지가 수신기에 들어가는 것을 방지하는 구실을 하는 방전관으로서, 송수신상자, 송수신스위치라고도 한다. 송수신 튜브는 강한 송신 공진 전파를 방전하여 비공진으로 하고, 약한 수신전파를 잘 공진하도록 한다.The transmission and reception tube is a discharge tube that serves to prevent transmission energy from entering the receiver, and is also called a transmission / reception box or a transmission / reception switch. The transmitting and receiving tube discharges the strong transmission resonance radio waves to make it non-resonant, and makes the weak reception radio waves resonate well.
이러한 송수신 튜브의 특성 및 고장유무를 시험하기 위하여 레이더로부터 송수신 튜브를 분리하여 시험장비를 이용하여 시험을 수행함으로서 레이더의 구조상 복잡성으로 인하여 분해와 조립에 과도한 시간의 소요와 정밀한 조립기술이 요구되는 단점이 있다.In order to test the characteristics of the transmission and reception tube and the presence of the failure by separating the transmission and reception tube from the radar to test by using a test equipment, due to the structural complexity of the radar requires excessive time and precise assembly technology required for disassembly and assembly There is this.
본 발명이 이루고자하는 기술적과제는 레이더의 구조가 매우 복잡하여 송수신 튜브의 제거와 조립이 많은 시간과 정밀한 조립기술이 소요되는 점을 고려하여 레이더에서 송수신 튜브를 제거하지 않고도 시험이 가능한 송수신튜브 검사장치 및 그 방법을 제공함에 있다.The technical problem to be achieved by the present invention is a transmission and reception tube inspection apparatus that can be tested without removing the transmission and reception tube in the radar in consideration of the fact that the structure of the radar is very complicated, the removal and assembly of the transmission and reception tube takes a lot of time and precise assembly technology And it provides a method.
상기 기술적과제를 해결하기위한 본 발명에 의한 송수신튜브 검사장치는 레이더에서 레이더신호를 송신시 송신신호를 수신하는 안테나, 상기 안테나로부터 수신한 신호를 전달하는 서큘레이터, 상기 서큘레이터로부터 출력된 신호를 수신하여 증폭하는 수신기 및 상기 수신기로부터 출력된 신호를 지연시켜 상기 서큘레이터를 통해 상기 안테나로 전송하는 지연기를 포함함을 특징으로 한다. Transmitting and receiving tube inspection apparatus according to the present invention for solving the technical problem is an antenna for receiving a transmission signal when transmitting a radar signal in the radar, a circulator for transmitting the signal received from the antenna, the signal output from the circulator And a delayer for receiving and amplifying the receiver and a delayer for delaying the signal output from the receiver and transmitting the delayed signal to the antenna through the circulator.
상기 다른 기술적과제를 해결하기위한 본 발명의 송수신튜브 검사방법은 (a)송수신 튜브 검사장비를 레이더의 안테나빔내에 위치시키는 단계, (b)상기 송수신 튜브 검사장비로 상기 레이더로부터 송신된 신호를 수신하는 단계, (c)상기 수신된 신호를 상기 레이더의 송수신 튜브의 이온화특성 시간만큼 지연하여 상기 레이더로 재전송하는 단계 및 (d)상기 (c)단계로부터 재전송된 신호를 상기 레이더가 수신하면 상기 송수신튜브는 정상이며, 상기 레이더가 수신하지 않으면 상기 송수신튜브가 고장임을 판단하는 단계를 포함함을 특징으로 한다.Transmitting and receiving tube inspection method of the present invention for solving the other technical problem is (a) positioning the transmitting and receiving tube inspection equipment in the antenna beam of the radar, (b) receiving the signal transmitted from the radar to the transmission tube inspection equipment (C) retransmitting the received signal by the ionization characteristic time of the radar transmission / reception tube to the radar, and (d) when the radar receives the retransmitted signal from the step (c). The tube is normal, and if the radar does not receive, characterized in that it comprises the step of determining that the transmitting and receiving tube is broken.
이하에서 도면을 참조하여 본 발명을 상세히 설명하기로 한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 3는 본 발명에 의한 송수신튜브 검사장치를 블록도로 도시한 것으로, 안테나(310), 서큘레이터(320), 수신기(330) 및 지연기(340)로 이루어진다.3 is a block diagram illustrating an apparatus for inspecting transmission and reception tubes according to the present invention, and includes an antenna 310, a circulator 320, a receiver 330, and a delayer 340.
안테나(310)는 레이더에서 레이더신호를 송신시 송신신호를 수신한다.The antenna 310 receives a transmission signal when transmitting a radar signal from the radar.
서큘레이터(320)는 안테나(310)로부터 수신한 신호를 수신기(330)로 전달하고, 지연기(340)로부터 출력되는 신호를 안테나(310)로 전송한다.The circulator 320 transmits a signal received from the antenna 310 to the receiver 330, and transmits a signal output from the delay unit 340 to the antenna 310.
수신기(330)는 서큘레이터(320)로부터 출력된 신호를 수신하여 증폭한다.The receiver 330 receives and amplifies a signal output from the circulator 320.
지연기(340)는 수신기(330)로부터 출력된 신호를 지연시켜 서큘레이터(320)를 통해 안테나(310)로 전송한다.The delay unit 340 delays the signal output from the receiver 330 and transmits the delayed signal to the antenna 310 through the circulator 320.
상술한 구성에 의거하여 본 발명의 동작을 설명하기로 한다.The operation of the present invention will be described based on the above configuration.
먼저, 레이더 시스템에 대하여 설명하기로 한다. 도 1은 레이더 시스템의 구성을 블록도로 도시한 것으로, 안테나(110), 송수신 튜브(120), 송신기(130), 수신기(140) 및 신호처리기(150)로 이루어진다. First, the radar system will be described. 1 is a block diagram illustrating a configuration of a radar system, and includes an antenna 110, a transmission / reception tube 120, a transmitter 130, a receiver 140, and a signal processor 150.
안테나(110)와 송수신기(130,140)사이에 송수신튜브(120)가 위치하여 송신기(130)가 송신시 수신기(140)를 보호하기 위하여 송수신 튜브(120)는 이온화되며 이것은 수신기(140)의 입력단을 단락시키는 역할을 수행하여 수신기(140)를 보호하게 된다. 신호처리기(150)는 수신기(140)로부터 수신된 신호를 분석하여 물체의 위치를 확인한다.Transmitting and receiving tube 120 is located between the antenna 110 and the transceiver (130,140) so that the transmitter and the receiving tube 120 is ionized to protect the receiver 140 when the transmitter 130 transmits, which is the input terminal of the receiver 140 The short circuit serves to protect the receiver 140. The signal processor 150 analyzes the signal received from the receiver 140 to check the position of the object.
도 2는 송수신 튜브의 특성도를 도시한 것으로, 레이더의 송신시 송신되었다가 송신이 종료되면서 송수신 튜브(120)는 전이기간(b)동안 전이를 시작하고 이 기간동안도 레이더는 수신이 불가능하며 이 전이기간(b)이 끝나야만이 레이더는 수신이 가능하게 된다. Figure 2 shows the characteristics of the transmission and reception tube, when the transmission of the radar is transmitted and the transmission is terminated, the transmission and reception tube 120 starts the transition during the transition period (b) and during this period the radar is impossible to receive This radar can be received only after this transition period b ends.
그러므로 이온화 특성시간(d)(이온화기간(a)+전이기간(c))이 송수신 튜브(120)의 성능을 확인하는 요소이다. Therefore, the ionization characteristic time (d) (ionization period (a) + transition period (c)) is a factor for checking the performance of the transmission and reception tube 120.
도 3에 도시된 본 발명에 의한 레이더 송수신 튜브 검사장치에 대하여 설명하기로 한다. The radar transmission and reception tube inspection apparatus according to the present invention shown in Figure 3 will be described.
레이더 송수신 튜브 검사장치는 레이더의 안테나빔내에 위치한다. 도 4는 레이더 송수신 튜브 검사장치가 레이더의 안테나빔내에 위치함을 도시한 것이다. The radar transmission and reception tube inspection apparatus is located in the antenna beam of the radar. Figure 4 shows that the radar transceiver tube inspection apparatus is located in the antenna beam of the radar.
그러면, 레이더에서 레이더신호를 송신시 송신신호를 송수신 튜브 검사장치의 안테나(310)로 수신한다. 상기 안테나(310)로부터 수신한 신호를 서큘레이터(320)를 이용하여 수신기(330)로 전달하고, 수신기(330)는 안테나(310)로부터 수신한 신호를 수신하여 증폭한다. 지연기(340)는 수신기(330)로부터 출력된 신호를 레이더의 송수신 튜브의 이온화특성 시간만큼 지연시켜 서큘레이터(320)를 통해 안테나(310)로 전송한다. Then, when the radar signal is transmitted from the radar to receive the transmission signal to the antenna 310 of the transmission and reception tube inspection apparatus. The signal received from the antenna 310 is transferred to the receiver 330 using the circulator 320, and the receiver 330 receives and amplifies the signal received from the antenna 310. The delay unit 340 delays the signal output from the receiver 330 by the ionization characteristic time of the transmission / reception tube of the radar and transmits the signal to the antenna 310 through the circulator 320.
그러므로 레이더로부터 송신된 신호가 레이더 송수신 튜브 검사장비의 지연기(340)를 거쳐 되돌아온 신호가 레이더에서 정상으로 수신이 되면 송수신 튜브는 정상이며 정상으로 수신되지 않으면 송수신 튜브는 고장으로 식별이 되게 된다.Therefore, when a signal transmitted from the radar is returned to the radar transmission and reception tube through the delay unit 340 of the test equipment is normally received in the radar, the transmission and reception tube is normal, if not received normally, the transmission and reception tube is identified as a failure.
본 발명에 의하면, 송수신 튜브를 레이더 시스템에 장착한 상태로 검사할 수 있으므로서 쉽고 빠르게 송수신 튜브의 고장 여부를 식별할 수 있다.According to the present invention, the transmission and reception tube can be inspected while mounted on the radar system, and it is possible to easily and quickly identify whether the transmission and reception tube has failed.
