Apparatus and method for avoiding interference among car radars based on fmcw waveform

PURPOSE: An interference exclusion apparatus and method of radar for a vehicle are provided to avoid interference between radars for the vehicle. CONSTITUTION: An interference exclusion apparatus(400) of radar for a vehicle comprises a GPS receiver(410), a waveform generator(440), a sensor(430), and a controller(420). The GPS receiver receives a GPS signal from a satellite. The waveform generator creates the waveform of a radar signal. The sensor senses the generation of interference between the radar signal outputted from the waveform generator and a circumlittoral radar signal transmitted from an interference exclusion apparatus of radar for another vehicle. The controller synchronizes time using the GPS signal inputted from the GPS receiver and creates a frequency hopping command to the waveform generator. The controller hops present frequency band of the radar signal to other frequency band when the sensor inputs an interference generation signal.
