This proposal describes our proposed technical approach, hardware and software development tasks, system integration and performance verification steps required to develop a prototype sensor for detection of buried bombs. The technique is based on utilizing the radar principles to construct a "ground penetrating electromagnetic transmitter and receiver" (GPR) and develop the associated multi-task software control and acquisition (signal processing) package. The proposed algorithm will enable acceptance of site specific data, by real time variation of frequency number, and capability to control the resonant frequency. To achieve the penetration of the transmitted signals to the desired depth and at the same time maintain a "safe" electromagnetic environment, to comply with the US Navy HERO requirements in the vicinity of sensitive weapons, the average transmitted power for the proposed system will be restricted to 0.1 watt. The software controlled, frequency signal receiver and transmitter, capability coupled with image processing "topography" should facilitate the ease of target (buried ordnance) recognition with sizes varying from 5-cm (2-in) to 200-cm (79-in), aspect ratios of 2 to 10, and depth region from 0.1-m (0.3-ft) to 50-m (164-ft). A series of field testing, at three different military sites, following completion of developmental tasks and system integration, will demonstrate and validate the overall capability of the system.
