Hierarchical Recognition of Ships at Sea using One-Dimensional Radar profiles

The proposed Phase II.5 work builds upon previous Phase II work for this SBIR program. MTSI will perform several tasks during the Phase II.5 program to extend the previous work and increase the Technology Readiness Level (TRL) to TRL 5. The previous Phase I and Phase II work applied probabilistic hierarchical Aided Target Recognition (AiTR) techniques against 1-dimensional radar data for a set of moving ground targets. During Phase II.5 we will extend our hierarchical AiTR technique to Government-furnished radar data for a target space consisting of ships at sea (SAS). MTSI will introduce decision confidence into the hierarchical AiTR algorithm as a part of the Phase II.5 work. We will perform hierarchical AiTR based on probabilistic feature extraction for the GFE SAS data. We will combine evidence using multiple extracted features to perform the hierarchical target identification. A further test of MTSI"s hierarchical AiTR algorithm will use the probabilistic output of a Navy target classifier in the hierarchical AiTR decision tree. Finally, we will ensure that all MTSI source code adheres to the NAVAIR Software Development Guidelines, version 1.3.
