Standoff range sense through obstruction radar system
First Claim
1. A method for operating a sense-through-obstruction radar system, comprising:
- receiving range information from a range finder associated with the sense-through-obstruction radar system, the range information describing a range to an obstruction;
transmitting the range information to a radar computing device, the radar computing device operable to utilize the range information to configure a timing of a transmit-receive cycle associated with the sense-through-obstruction radar system;
receiving track data corresponding to a filtered range/range-rate pair from the radar computing device; and
causing at least one track box to be superimposed over a real-time image that represents a field of view of the sense-through-obstruction radar system, the at least one track box corresponding to the track data and representing a target detected by the sense-through-obstruction radar system, wherein the obstruction is between the target and the sense-through-obstruction radar system.

Abstract
A standoff range, sense-through-obstruction radar system is capable of detecting micro-Doppler, or life form signatures, and movements through obstructions at stand-off ranges and displaying the target information over a live video feed of the area under surveillance. The sense-through-obstruction radar system comprises an antenna assembly that includes a horn antenna and a reflector configured to reflect radio frequency (RF) energy to/from the horn antenna. An antenna pointing assembly supports the antenna assembly. The antenna pointing assembly is configured to move the antenna assembly to point the antenna assembly toward an obstruction. A sensor assembly is mounted to the antenna assembly so that the sensor assembly is aligned with the RF beam formed from the RF energy reflected from the reflector to the horn antenna. The sensor assembly is configured to detect the location of the obstruction and to provide information to assist pointing of the antenna assembly toward the obstruction.
