Optimized vehicle-borne radar operation based on return-signal character

Abstract

A navigation system for a vehicle is disclosed, the system includes a radar antenna array and a radar operating system. The radar antenna array transmits and receives SPR Antenna radar signals, and includes a plurality of channels each including transmit and receive Array functionality. The radar operating system drives the antennas to emit radar signals and receives reflection signals at least partially from beneath the vehicle. The radar operating system (i) assess a complexity of signals received via each of the channels and, if the signal complexity associated with a channel falls below a threshold, reduces an operating parameter associated with that channel and (ii) periodically localizes the vehicle based at least in part on the received radar signals.
