Ultra wideband (UWB) automotive radars, less expensive than conventional millimeter-wave radars, have attracted attention from the viewpoint of reducing traffic accidents. The performance of automotive radars is degraded by interference from nearby radars operating at the same frequency. We assumed a scenario where two cars pass each other on a road. The desired-to-undesired signal power ratio (DUR) was found to vary approximately from −10 to 30 dB when employing cross polarization. Allocation of different maximum length sequences to different radars facilitates suppression of interference from other radars. Probabilities of false alarm (Pfa) and detection of the passing car (Pd) were evaluated by simulation. It was found that Pd = 0.995 and 0.993 for Pfa = 10−2 and 10−4, respectively, when DUR = −10 dB (the worst prediction).
