RADAR FOR BEING EQUIPPED TO WEAPON SYSTEM ON THE GROUND AND A METHOD FOR SUPPRESSING FREQUENCY INTERFERENCE BETWEEN ADJACENT RADARS USING THE SAME RADAR, CAPABLE OF ENCODING S SIGNAL IN A PULSE PHASE CODING

摘要

PURPOSE: A radar for being equipped to weapon system on the ground and a method for suppressing frequency interference between adjacent radars using the same radar are provided to prevent fundamentally the frequency Interference between radars by processing a signal by receiving the coded signal in the pulse phase coding scheme and decoding the received signal.;CONSTITUTION: A pseudo noise code generator(301) codes a transmitted signal, and generates a code corresponding to the specific phase of the transmission signal. A frequency synthesizer(302) generates an RF frequency for the up-converting of the transmission signal and an intermediate frequency for the down-conversion of the received signal. A transmitter(303) changes the transmission signal into the radio frequency signal. A phase shifter(304) is inputted with the PN code and the radio frequency signal. The phase of the radio frequency signal is varied according to the PN code. A digital signal processor(309) implements the signal processing algorithm through the restored signal. A target is detected.;COPYRIGHT KIPO 2010
