Cases of interference between pulsed radars, frequency-modulated continuous wave and noise-modulated automotive radars at frequencies around 24 and 77 GHz are considered, and it is shown that pulse- and frequency-modulated waveforms are very robust to interference from each other if the radar receiver is properly designed. Noise modulations are much harder to handle efficiently. Interference from other sources and the potential for deliberate jamming are also considered.
