RADAR SYSTEM AND METHOD FOR SIGNAL PROCESSING USED THEREOF

摘要

PURPOSE: A radar system and a method for processing signal using the same are provided to reduce detection error for the distance and the speed of a target by omitting the jamming signal or other radar signal while beat frequency and Doppler frequency are extracted from target reflective signal. CONSTITUTION: A signal generator(20) generates target detection frequency signal and the complex conjugated signal of the target detection frequency signal. A noise phase signal generator(30) generates noise signal for a phase modulation and a phase demodulation. A frequency modulation and demodulation signal generator(50) generates frequency modulation signal and frequency demodulation signal. A first modulation mixer(40) mixes the target detection frequency signal and the noise signal for the phase modulation in order to modulate the phase of the target detection frequency signal. A second mixer(60) mixes the phase-changed target detection frequency signal and the frequency modulation signal in order to modulate the phase-changed target detection frequency signal to wireless frequency signal.
