Systems and Methods for Correcting for Leakage and Distortion in Radar Systems

摘要

Methods and systems for correcting leakage and/or distortion in radar systems include defining an integration time period, dividing the integration time period into a first sub-period and a second sub-period, at least partially transmitting a transmission radar signal during the first sub-period of the integration time period, not transmitting at all during the second sub-period of the integration time period, integrating the detected signal during both the first sub-period and the second sub-period, and subtracting a last sampled integrated value of the second sub-period from a last sampled integrated value of the first sub-period to generate a corrected integrated value for the integration time period.

1. A method of correcting for leakage in a radar sensor system, comprising:
defining an integration time period, the radar sensor system being configured to integrate a detected signal during the integration time period; dividing the integration time period into a first sub-period and a second sub-period, the radar sensor system at least partially transmitting a transmission radar signal during the first sub-period of the integration time period, and the radar sensor system not transmitting at all during the second sub-period of the integration time period; integrating the detected signal during both the first sub-period of the integration time period and the second sub-period of the integration time period to generate a plurality of sampled integrated values; and subtracting a last sampled integrated value of the second sub-period of the integration time period from a last sampled integrated value of the first sub-period of the integration time period to generate a corrected integrated value for the integration time period.
