Innovative techniques for radar high angle resolution are proposed for investigation in a Phase I effort to enable the resolution of the direction of arrival (DOA) of returns from multiple targets that fall within one beam width and within the same range and Doppler Cells. The techniques proposed emphasize the pursuit for optimal utilization of available aperture space, by a combination of arrangement of antenna elements and advanced, sophisticated signal processing techniques, implemented in state-of-the-art technologies that enable their realization for the maximum achievable performance. Alternative approaches are described which hold significant promise for realizing the objectives of the subject SBIR topic. It is proposed to explore these approaches analytically for the radar application, and generate conclusive expressions and quantitative illustrations for meaningful comparisons and analytical proofs of concepts/techniques. Implementation design analyses will be performed that will define the trade-offs and the technical risk for ultimate developments. Definitive high angle resolution techniques will be formulated, performance predictions will be derived, implementation latitudes will be established, and a plan for proof-of-technique experiments and hardware development program for Phase II.
