Abstract
Embodiments relate to radar systems and methods. In an embodiment, a system includes a radio frequency (RF) sensor array comprising a plurality of spaced apart sensors; and a reflector element positioned proximate the RF sensor array to reflect waves toward the RF sensor array. In an embodiment, a system includes an antenna array comprising a transceive antenna and a plurality of receive antennas; a mirror arranged proximate the antenna array; a voltage controlled oscillator (VCO) configured to generate a signal to be transmitted by the transceive antenna; and a controller configured to resolve signals received by the plurality of receive antennas to determine an angular position of a target, wherein the signals received include a first portion of the signal reflected by the target and a second portion of the signal reflected by the target and the mirror.
