<p>PURPOSE:To obtain a radar apparatus with a hardware amount of a demodulator reduced. CONSTITUTION:A modulator 5 creates a transmitted signal from a COHO (coherent oscillator) signal output from a coherent oscillator 3 and a pseudo random code output from a code generator 4. A duplexer 2 switches over the transmission and reception of an antenna 1. A demodulator 9 uses the pseudo random code integrated by an integrator 8 to perform demodulation processing to a received signal via a phase detector 6 and an A/D converter 7. A display 11 displays a target detected by a search signal processor 10 from the received signal. By demodulating the received signal by a single demodulator, a hardware amount of the demodulator can be reduced.</p> |
