Abstract: 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.

Abstract: A radar system and method include a first transmitted radar signal having a first frequency and a second transmitted radar signal having a second frequency different from the first frequency. A receiver receives reflected radar signals generated by reflection of the transmitted radar signals and generates receive signals indicative of the reflected radar signals, a first receive signal being indicative of a first reflected radar signal generated by reflection of the first transmitted radar signal, and a second receive signal being indicative of a second reflected radar signal generated by reflection of the second transmitted radar signal. A processor receives the first and second receive signals and computes a difference between the first and second receive signals to generate a difference signal, the processor processing the difference signal to provide radar information.
