Cancellation System for Millimeter-Wave Radar

摘要

In a millimeter-wave radar, full-duplex operation is achieved by measuring a time interval during which a leakage signal is present in a digital baseband received signal, generating samples of the digital baseband received signal, and masking a subset of the samples corresponding to the time interval, which removes the leakage signal from the digital baseband received signal. The step of measuring the time interval may be performed during a calibration phase during which desired signals are suppressed.

1. In a transceiver, a method comprising:
sampling a corrupted signal comprising at least one desired signal and a leakage signal for producing a digital baseband received signal; determining a time interval during which the leakage signal is present in the digital baseband received signal; and removing a subset of the samples corresponding to the time interval for producing a masked digital baseband received signal having improved signal to noise.
