Personnel Identification and Location for MOUT Applications

A need exists to simultaneously mitigate/cancel interference due to sidelobe andmainlobe jamming and clutter. Practical signal processing techniques withapplication to existing radars (such as the SPY-1) are required. In this proposalISL addresses this need by examining two approaches. 1) the use of spatial-onlyadaptive array processing (followed by Doppler or MTI processing) and 2) space-timeadaptive processing (STAP). Each technique will be enhanced by the delta-deltachannel, which is currently available but unused on the SPY-1 radar. ISL willexplore past related efforts to examine both the spatial and STAP techniques, andcompare these techniques in terms of performance and cost/risk of implementation.The spatial-only techniques offer the potential for low-cost, low-riskimplementations, however are limited by the number of jammers that can besimultaneously mitigated. STAP offers the potential to simultaneously mitigatea larger numbers of jammers at the cost of increased computational requirements.ISL's site specific radar simulation capabilities will be used extensively in thealgorithm development and evaluation.The proposed work will benefit many DoD users requiring advancedinterference mitigation technology/algorithms. Allshipboard and theater/battlefield array radars (e.g., SPY-1, TPS-59, TPS-70,Patriot, and THAAD) can potentially benefit from this technology as a result ofimproved robustness to interference and improved target resolution.
