1. A passive radar receiver system comprising:
a radio frequency (RF) receiver front-end configured to receive a wireless source signal provided from a transmitter and a reflected signal of the wireless source signal reflected from a target in a region of interest, the RF receiver front-end configured to be coupled to a plurality of antennas, and comprising a receiver chain, and an antenna switch, the antenna switch being configured to switch a first one of the plurality of antennas to be coupled to the receiver chain during a first time to generate first radar signal data based on a combined wireless signal comprising the wireless source signal and the reflected signal during the first time, and to switch a second one of the plurality of antennas to be coupled to the receiver chain during a second time to generate second radar signal data based on the combined wireless signal during the second time; and
a signal processor configured to generate source signal data associated with the wireless source signal based on the first and second radar signal data and to generate reflected signal data based on the first and second radar signal data, and to generate target radar data associated with the target based on the source signal data and the reflected signal data.
