Extended Virtual Array In An Automotive MIMO Radar

Abstract: a novel and useful system and method for extending the virtual array of an existing memo automotive radar. in one embodiment, the virtual array is extended by adding one or more additional tx or rx antennas to the existing radar thereby improving the resolution in either azimuth or elevation or both. the additional antennas are added via one or more extender printed circuit boards (pcbs) that are connected to the main radar pcb. the one or more extender pcbs include the additional tx or rx antenna arrays and are adapted to be a set fixed distance an orientation from the main pcb in accordance with the desired virtual array. the one or more extender pcbs and main pcb are mounted in housings that are rigidly mechanically connected to each other. the local oscillator (lo) signal generated on the main pcb is fed to the one or more extender pcbs via any suitable signal connection including rf, electrical, or waveguide connections.
