Abstract

PURPOSE: To enable an optimum integration value to be specified and detection probability to be improved by determining the optimum integration value from S/N per pulse of a received signal according to a bandwidth of a Doppler spectrum of the received signal.
CONSTITUTION: An A/D converter 1 converts a received signal to a digital signal. Then, each range pin 2 divides the digital signal from the converter 1 for each distance to a target. Each received signal bandwidth measurement means 8 measures the bandwidth of a Doppler spectrum of the received signal from an output signal of each pin 2. Then, a coherent integrator 7a determines an optimum integration value from S/N per pulse of received signal which is output from each pin 2 according to the bandwidth of Doppler spectrum of the received signal which is output from the means 8. Then, a non-coherent integrator 5 allows output signal of each amplitude detector 4 to be subjected to non-coherent integration. Then, a threshold detector 6 detects presence of an object to be detected when the output signal of the integration 5 exceeds a threshold level.
