Abstract
An extensive comparison on radar-to-radar interference in frequency-modulated continuous wave (FMCW) and binary phase-modulated continuous wave (PMCW) radars is performed. The noise-plus-interference power for FMCW-to-FMCW and PMCW-to-PMCW interference in a single victim and single interferer environment is compared for generalized waveform-based scenarios. It is proven that the interference suppression is equal in FMCW and PMCW radars in case the time-bandwidth product in both systems is equal.
