To satisfy the requirements of adaptive signal processing for radar reconnaissance in modern complex electromagnetic environment, several adaptive signal processing frameworks are studied based on the modeling and analysis of radar reconnaissance problem. For signal processing modules and algorithms, structures such as adaptive feature detection and analysis frameworks, and adaptive signal deinterleaving framework are designed to enhance the capabilities of processing newly emerging low probability of recognition signals. For signal processing flow of the reconnaissance system, the capabilities of dynamic situation awareness are expanded based on corresponding adaptive tracing and prediction frameworks. For the cooperation between a radar reconnaissance system and other subsystems, adaptive cooperation frameworks are designed to work together with a radar system and a jamming system respectively for different requirements, so that the overall operational effectiveness is improved. It is assumed to provide some helpful ideas for further researches in adaptive radar countermeasures.
