PMCW: Revolutionizing Radar Sensing
PMCW radars, or Phase Modulated Continuous Wave, is a game-changing technology that offers significant advantages over the traditional Frequency Modulated Continuous Wave (FMCW) radar, which is commonly used by almost all current radar manufacturers. Let's delve deeper into the benefits of PMCW radar!
Digital vs. Analog: Improved Accuracy
Unlike FMCW radars that uses the frequency difference between transmitted and received signals as an indirect way for range detection, PMCW radars employ digital code correlation, providing a direct way. This eliminates the need for strict linearity in frequency ramping over time, which is a huge challenge in analog circuit design for FMCW radars. Consequently, PMCW radars exhibit significantly lower error rates in range detection.

Frequency Modulated Continuous Wave (FMCW) radar identifies targets by the frequency difference between sent and received signals. This method faces two issues: firstly, in detecting multiple static targets, overlapping sidelobes increase false alarms; secondly, high sidelobes can hide weaker targets, limiting the radar's ability to detect both strong and weak targets simultaneously.

PMCW radar, utilizing high-speed ADC, directly measures the delay between transmitted and received signals and significantly reduces sidelobes with phase-coded modulation waveforms, addressing the static target issue inherent in FMCW radar. Thus, PMCW radar offers notable advantages over FMCW, including higher precision, lower false alarms, and a broader dynamic range.
