Abstract: The technology of the passive radar based on non-cooperative radar illuminator is summarized,and the research history and current situation of this field are introduced,then the primary principle of a non-cooperative bistatic radar system is analyzed.The main content contains the basic geometrical relationship,signal energy relationship,receiver structure,parameter measurement and target location method.Finally,several key techniques of the system,such as the signal analysis and optimal selection of radar illuminator,system synchronization,direct-path reference signal reconstruction,weak target signal detection and parameter estimation,and target tracking,data fusion and target recognition,are also analyzed.
