Optimizing Single Sweep Range and Doppler Processing for FMCW Radar using Inverse Filtering
other
We discuss range and Doppler processing for FMCW radar using only a single pulse or frequency sweep.
The first step is correlation processing, for which the range and Doppler resolution are limited by the
ambiguity function. We show that this resolution can be optimized with an additional inverse filtering step.
The method is demonstrated for sinusoidal FMCW radar measurements. Several regularized inverse
filters were compared and the non-adaptive pseudo inverse filter gave the best results.
