Claim:
1. A high definition RF radar system for an autonomous vehicle, the system comprising: a first array and a second array, the first array comprising a first plurality of receive antenna elements provided by a first receive switch network and a first plurality of transmit antenna elements provided by a first transmit switch network, and the second array comprising a second plurality of receive antenna elements provided by a second receive switch network and a second plurality of transmit antenna elements provided by a second transmit switch network; a Boolean associator configured to receive data from the first array and the second array and determine that the received data represents a true target detection of an object, wherein the Boolean associator is configured to determine the true target detection and target position when a plurality of constraints are met, the plurality of constraints including at least one first type of constraint and at least one second type of constraint; and a scene imaging unit, the scene imaging unit being configured to receive a plurality of true target detections and target positions from the Boolean associator and provide at least one of object detection information and scene imaging information to one or more systems of the autonomous vehicle; wherein the first array is disposed on the autonomous vehicle with a first orientation such that the first plurality of receive antenna elements and the first plurality of transmit antenna elements are configured for detection in a first direction; wherein the second array is disposed on the autonomous vehicle with a second orientation such that the second plurality of receive antenna elements and the second plurality of transmit antenna elements are configured for detection in a second direction; and wherein the first array is oriented generally orthogonal to the second array.
