Background technology
Known shipborne radar (BrP No.2177566), wherein in order to increase from the quantity of the pulse of target reflection, emission two or some beams have been proposed, these beams are separated out in the leveling board (horizontal plate on a comer) of corner, and the width of beam is suitable.The deficiency of this judgement is that it does not increase data update rate.
With the immediate analog of disclosed invention (prototype) be the 3-D radar AN/SPS-48E (according to the catalogue 1997-1998 of the naval of world's naval weapon system association's guide (The NavalInstitute Guide to World Naval Weapons Systems)) of USN.Radar AN/SPS-48E represents only to be operated in the single channel workstation of a position of frequency range.Radar AM/SPS-48E rotates by the circumferential motor that utilizes antenna in the leveling board and scans one or one group of beam, and carries out the space inspection in vertical panel (vertical plate).Antenna equipment has hole, slit (slot-hole) structure of waveguide.Carry out and wave (roll) and face upward the stable of bow (pitch) relevant antenna beam pattern by the electronics mode.The operator scheme that depends on radar, emitter produce have height, the corresponding beam of medium or low emissive power.The basic shortcoming of radar AN/SPS-48E is quite low data update rate, and can not detect the target in low-latitude flying.Distinctive deficiency can cause reducing of tracking stability, and the scope of target indication transmission and the minimizing of degree of accuracy.
Summary of the invention
The objective of the invention is to develop a kind of radar workstation, it has the pinpoint accuracy that data update rate, coordinates of targets are measured and the target indication transmits of increase, the sensing range of increase, comprises the undersized target of low-latitude flying.Compare with prototype, distinctive purpose is to realize by the radar with two channel architectures, wherein by two independently channel realize the emission of detectable signal and from the reception of the signal of target reflection.Two frequency channels structurally are identical, and are operated in two frequency subrange places that separate of E band in the common issue RX path.Each channel has the device that transmits and receives of transmit receive antenna, HF signal.Because structurally being provided with two frequency channels adds up and segmenting device, so be provided at two independent operations that separate the radar in the subrange frequency.The antenna that transmits and receives of Radar channel opens toward each other, makes to lead them from the signal of their emissions in relative direction mutually, and transmits and receives antenna and be installed on the general stable frame with the IFF antenna.The abundant mechanically stable of the turning axle of the antenna of Radar channel and IFF system will be eliminated the influence to the radar characteristic of waving of ship.Owing to have the formation of the beam pattern of low secondary lobe (side-lobes) level, realized the pinpoint accuracy that the target indication transmits.Utilize the operation of two frequency channels allow to get rid of seriously invalid in the detection of the aerial target of low-latitude flying, and data update rate has been increased twice.
By electron scanning, utilize two Radar channel to carry out space inspection to the mechanical rotation of antenna in beam in the vertical panel and the leveling board.According in variation, carry out the scanning of vertical panel corresponding to the transmit frequency signal under the specific program of the operator scheme of establishing.Scanning sequence is set order and the various detectable signal that beam is followed.Measure desired degree of accuracy for the energy potential and the scope that realize necessity, use synthetic detectable signal with linear frequency modulation (LFM).Control the control of carrying out recurrence interval, recurrent frequency and power that transmits and kind by display unit and pattern; this control makes emitted energy in the spatial distributions optimization, and the spatial placement that allows to depend on barrier is used the interference protection resource effectively.In order to increase service efficiency, in radar, the great majority in the selection of control, scan control, signal kinds and the disposal route thereof of interaction, applicability and the fault search of automatic realization operation switching, various devices.For same purpose, depend on the problem that workstation is solved at present time durations, the various patterns that the application space is checked, the i.e. algorithm of the formation of beam motion, signal and processing.Agreement cut off from the antenna to the emitter and emitter to opportunity of the connection of " illusory antenna ".
