Innovative Non-GPS Geolocation Technologies for Hand and Remotely Emplaced Munitions

A revolutionary non-GPS solution for geolocation for hand and remotely emplaced munitions is proposed. Novel, paradigm shifting technologies of RF polarized scanning and cavity sensor based direction of arrival are merged to enable discovery of emplaced munitions within a minimum zone of 10 kilometers. The spatial precision is better than 100 cm. The proposed solution naturally consumes low power. Embedding antennas into the munition ensures that the electronics occupy a volume which is less than 1 cubic inch. A single electronic scanner solution is sufficient to address the objectives of solicitation, minimizing the burden of transportation and deployment. The deployment has an extremely low probability of detection. An encrypted, low power, high speed, point-to-point, wireless link can be established with the host station for communication as needed. The scanner provides programmable capability to periodically monitor the unauthorized movement of the emplaced munition, and thus an accurate map of the emplaced munitions is always available to the host. The proposed system meets the operational time and shelf life requirement of over 20 years.
