Abstract

PURPOSE:To improve the stability of a transmission frequency by detecting the fluctuation of the frequency when it is transmitted and by compensating the fluctuation at the stage of processing a reception signal. CONSTITUTION:A directional coupler 11 takes out a part of a transmission signal. This signal is converted into a signal in an IF band by a mixer 12 and a phase difference between the latter and the COHO signal of a COHO oscillator 1 is detected by a phase detector 13. A signal detected by the phase detector 13 is compared with a signal free from the fluctuation of a frequency in an MTI processing circuit 14, and imformations on the degree of deviation and the direction thereof are stored inside the MTI processing circuit 14. Signals radiated into the air in this state are received one after another, subjected to phase detection through the route of circuit elements 5-9 and inputted in the MTI processing circuit 14. The modification of the input is performed there in accordance with the degree and direction of the deviation already memorized.
