ABSTRACT:
Three methods are used to minimize the interference between multiple FMCW radars. The first, basic method is to use spread spectrum waveforms which differ for each radar. The FMCW waveforms have different modulation slopes for each frequency excursion. The waveforms also have different center frequencies for each excursion thus in total spreading the spectrum in frequency and modulation slope. The second method used is to control the power output for FMCW radars which have narrow beam scanning antennas, according to the azimuth position of the antenna. The third method is to select separate frequency bands for any interference which would still be above threshold. Selection would be by either infrastructure information or by comparison of "own" radar code to that received from each interfering radar over a separate, but related modulated CW transmission.
