1. A method of wireless communication at a first user equipment (UE), comprising:
receiving an indication of a location of a second UE and an indication of one or more parameters associated with radar transmissions from the second UE;
receiving a radio frequency waveform comprising a first component associated with the radar transmissions from the second UE and a second component associated with reflected radar transmissions from the first UE;
compensating for an interference from the first component of the received radio frequency waveform based at least in part on the location of the second UE and the one or more parameters associated with the radar transmissions from the second UE, wherein compensating for the interference comprises:
generating a frequency spectrum based at least in part on the received radio frequency waveform; and
identifying, after the generating, a portion of the generated frequency spectrum that comprises the interference from the first component of the received radio frequency waveform based at least in part on the location of the second UE and the one or more parameters associated with the radar transmissions from the second UE; and
generating a radar image from the received radio frequency waveform based at least in part on compensating for the interference from the first component of the received radio frequency waveform.
