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 60GHz
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.
