Abstract: An apparatus for is disclosed for precoding radar receive signals. The apparatus includes a wireless transceiver configured to transmit a radar transmit signal using at least one antenna. The radar transmit signal is modulated in frequency across multiple cycles based on one or more frequency-modulation schemes. The wireless transceiver is also configured to receive at least two radar receive signals using at least two other antennas. The at least two radar receive signals include versions of the radar transmit signal that are reflected by at least one object. Each of the at least two radar receive signals is modulated in frequency across the multiple cycles based on the one or more frequency-modulation schemes of the radar transmit signal. The wireless transceiver is further configured to precode the at least two radar receive signals across the multiple cycles to generate precoded radar receive signals that are orthogonal to each other.
