Knowledge-based space-time adaptive processing

Abstract

This paper describes an innovative concept for knowledge-based control of space-time adaptive processing (STAP). The knowledge-based approach holds potential for significant performance improvements over classical STAP processing in non-homogeneous environments by taking advantage of a priori knowledge. Under this approach, knowledge-based control is used to direct pre-adaptive filtering, and to carefully select STAP algorithms, parameters, and secondary data cells.
