Original Abstract Submitted
certain aspects provide a method for object detection. the method generally includes: transmitting, via a first antenna, a transmit signal generated via a first transmit chain, the transmit signal being generated based on a mixer output signal; receiving a first receive signal via a first receive chain coupled to a second antenna, the first receive signal being associated with the transmit signal; generating, via a first phase shifter, a first phase-shifted signal based on an adjustment signal received via a signal path coupled to the first transmit chain, the adjustment signal being generated based on the mixer output signal; combining the first phase-shifted signal and the first receive signal to generated a combined receive signal, wherein a phase-shift setting of the first phase shifter is controlled based on at least one of a mutual coupling component or a phase noise of the combined receive signal.
