Abstract

PURPOSE: To obtain a transmission signal corresponding to the target signal rapidly with a high precision, by acquiring the target signal by the receiver for monitor and by controlling the local oscillating part of the transmission frequency on a basis of this signal.
CONSTITUTION: Transmitter and receiver 2, which has local oscillator 211 controlled by signals applied from other parts, reference oscillator 215 which shifts the oscillation output signal by a prescribed frequency to output a sample signal, continuous signal generating circuit 214 including the narrow-band width analysis receiving circuit operated on a basis of the local oscillation output signal, and modulation amplifier 222, and monitor receiver 1 which has analysis receiving circuit 12 which analyzes the wide-band receiving signal to acquire the target signal adapted to prescribed conditions and extracts difference information among various sources including the frequency, the sample signal, and the target signal to form the control signal to local oscillating part 211 are provided. Then, the prescribed target signal is extracted to control the local oscillation frequency into a required value.
