description Techniques provided herein are directed toward enabling short-range proximity detection using radar sensors by reducing or eliminating OTA leakage. Embodiments generally include performing spatial cancellation by using a plurality of transmit/receive pairs of antenna elements to implement analog and/or digital leakage cancellation on the transmit and/or receive side. According to some embodiments null space projection cancellation, OTA leakage tracking, or adaptive minimum variance distortionless response (MVDR) beamforming may be performed to help preserve of the OTA leakage cancellation efficacy over time.
