This monograph presents material devoted to the art of Radar Electronic Counter Counter Measure (ECCM). Modern electronic warfare encounters are very devastating and are terminal in deciding the course of a major conflict. Thanks to the all pervading computer technology and highly developed software support, modelling and simulation are the tools for the present day designers. The book represents the author's attempts in modelling the different aspects of radar ECCM the logic, the process and the controversy involved. It also dwells on the vagaries encountered in estimating and evaluating the efficacy of Radar ECCM solutions against ECM threats, while under different operational scenario.
