Abstract:

A system for navigating a vehicle on a terrain includes a surface-penetrating radar (SPR) system having one or more micro-antenna array having a full frequency range for acquiring real-time SPR information associated with the vehicle and one or more controllers configured to determine information associated with the terrain and/or the vehicle based at least in part on the acquired real-time SPR information. In various embodiments, the micro-antenna array(s) includes multiple micro-antenna elements, each being configured to operate at a frequency range, the frequency ranges of the micro-antenna elements collectively spanning the full frequency range greater than the frequency range of an individual one of the micro-antenna elements.
