Vehicle-mounted ultra-wideband radar systems and methods
First Claim
1. A method of detecting mines and/or improvised explosive devices, the method comprising:
- tracking distance data;
collecting range-magnitude radar data from substantially forward-looking bistatic antenna transceivers capable of operating over two channels, a first transceiver capturing radar data for a first area and a second transceiver capturing radar data for a second area;
deriving range resolution data and cross-range resolution data from the range-magnitude radar data;
focusing the range resolution data and the cross-range resolution data, based at least on the distance data and an antenna beamwidth pattern associated with the antenna transceivers; and
,anding data for portions of the first area and the second area that overlap.

Abstract
Vehicle-mounted UWB systems and/or methods for detecting mines and other explosive devices are provided. In certain exemplary embodiments, a system for detecting non-buried mines and/or improvised explosive devices is provided. Distance measuring equipment may be configured to track movement of the system. Substantially forward-looking bistatic antenna transceivers may be capable of collecting range-magnitude radar data over two channels. A first transceiver may capture radar data for a first area, and a second transceiver may capture radar data for a second area. A processor may be configured to: derive range resolution data and cross-range resolution data from the range-magnitude radar data; focus the range resolution data and the cross-range resolution data, based at least on the distance data and an antenna beamwidth pattern associated with the antenna transceivers; and, “and” data for portions of the first area and the second area that overlap.
