Low Probability of Intercept Sense Thru Wall Radar


TECHNOLOGY AREA(S): Electronics, 

OBJECTIVE: Build and demonstrate a Low False Alarm, Low Probability of Intercept (LPI), Thru Wall Radar System 

DESCRIPTION: U.S. Army requires the tactical capability to quickly detect, locate, and discriminate hidden chambers and people. The automated sensor system must be able to distinguish between a normal space, for example the space between wall studs, and an occupied space to enable the operator to quickly focus their Sensitive Site Exploitation (SSE) operations. The system needs to operate with various common building materials, including brick, cinder block, concrete, wood, sheet rock, etc. The system needs to be automated, easy to operate, and not require specialized technical training to interpret. The urban Warfighter must be able to increase his/her situational awareness in an expeditious manner. This proposal will enable non-wall contact detection of hidden chambers and personnel. Critically important in sense thru the wall programs is achieval of a low false alarm rate due to complex clutter environments and multi-path. Thru Wall Radar System must be immune to interference (e.g., simple jammers). The radar signals must also be Low Probability of Intercept (LPI) and Low Probability of Detection (LPD). 

PHASE I: Offeror will demonstrate their knowledge and understanding of state-of-the-art RF systems and their practical application. Offeror will highlight their understanding of operational parameters facing the dismounted and mounted Soldier, as it relates to thru wall detection, in the modern Army. The Offeror will design a radar system with LPI/LPD characteristics and low false alarm rate. 

PHASE II: Design, develop, build, and test a mounted and dismounted RF prototype radar for thru wall applications. 

PHASE III: Offeror will work with the Army and industry partners to create a commercialization and manufacturing plan for the system to support fielding by an Army program of record. The Offeror will illustrate a comprehensive commercialization program plan to ensure transition of the technology from military to commercial application.
