Detection and Tracking of Small Boats and Semi-Submersibles in the Littoral

We propose to develop an innovative adaptive array processing and CFAR detection technique for the detection, discrimination, and tracking of small vessels in high sea state. The proposed technology will use MTI array processor/adaptive CFAR detector with time-varying (temporal) Doppler signatures to characterize small vessels and sea clutter. We will perform detailed analysis and modeling to assess the feasibility of the array processor/CFAR detector. Temporal Doppler features of vessels will be used as new features for the detection and discrimination. During Phase I, the adaptive array processor and data driven CFAR detector will be developed along with an architecture and an approach for implementing the architecture on current radar system. The transmitter/receiver array provides electronic steering and beam-forming. During Phase I Option, we will develop detailed designs for the components of the array processor/CFAR detector, investigate the use of wakes for vessel features and the use of two-site radar system for estimating motion kinematics of the vessel. During Phase II we will verify the detailed design, layout the components, simulate for functionality and timing, test the performance and reliability of adaptive processor/detector, and verify the entire radar adaptive processor/detector design.
