An apparatus for detecting an object in a detection area of a wireless power transfer system is provided. The apparatus comprises a receiver configured to receive a plurality of radar signals from a radar transceiver. The apparatus comprises a processor configured to convert the plurality of radar signals to a plurality of digital radar signals. The processor is configured to bandpass filter the plurality of digital radar signals. The processor is configured to remove frequency content below a first threshold frequency common to at least two consecutive digital radar signals of the plurality of digital radar signals. The processor is configured to down-convert the plurality of digital radar signals into a plurality of complex digital baseband signals. The processor is configured to detect a range, a speed, and a direction of the object in the detection area based at least in part on the plurality of complex digital baseband signals.
