Özet
This paper evaluates the performance of slow-time coded MIMO and phased array radars under transmitter and receiver phase noise. Utilizing a genie-aided joint angle-Doppler processing framework, we compare the SINR performance of both architectures in interference-rich environments. Numerical results indicate that while both systems degrade under high phase noise, MIMO radar exhibits superior angular selectivity and faster SINR recovery in clutter. These benefits are attributed to the waveform diversity and increased degrees of freedom provided by slow-time coding, which improves directional interference mitigation over single-waveform phased array systems.
