Analysis of the Interception Ability of Electronic Reconnaissance Satellite on Ground-based Radars

After the detailed analysis of the application of electronic reconnaissance satellite in peacetime and wartime, this paper puts forward the effectiveness index and calculation model (reconnaissance minimum power) of the interception ability of electronic reconnaissance satellite on ground-based radars, considering if radiation signals of ground-based radars can be effectively intercepted by electronic reconnaissance satellite. Furthermore, this paper sets the typical tactical scenario in which HEO, LEO electronic reconnaissance satellites implement surveillance on ground-based warning radars and guided radars, and then quantitatively calculates the reconnaissance minimum power of two kinds of electronic reconnaissance satellites on typical ground-based radars operating in different power gears. The analysis of examples show that the effectiveness index and calculation model is reasonable and effective, providing a better tool for ground-based radars’ quantitative analysis on the space-based electronic reconnaissance threats.
