Abstract

This work presents multiple concepts for spectral equalization in pulse-modulated continuous wave (PMCW) radar systems in order to restore the received signal for improved correlation results. Two concepts for postprocessing are presented which use the spillover signal for calibration. A third concept is introduced which uses a predistorted transmit signal and thus does not require spectral equalization in the receiver. The concepts are verified through measurements using a 60 GHz transceiver together with digital-to-analog converters (DACs) and analog-to-digital converters (ADCs) operating at 4 GSa/s, resulting in a range resolution of under 4 cm.
