Modeling and Calculation of High Power Electromagnetic Pulse Interference on Radar
The high power electromagnetic pulse (EMP) withsufficient radiating energy can penetrate and interfere on allkinds of radars.This paper studies the interference effect ofhigh power EMP on paraboloid radar and AESA radarrespectively.The coupling EMP (5us duration) energy via mainlobe and side lobe into a paraboloid radar antenna is calculated.The distance and other parameters at which the sensitivecomponent in radar front end can be damaged are presented.The coupling probability of EMP (single pulse and pulse trains)into the radar antenna in scanning state via main lobe or sidelobe is studied and modeled.Finally,high power EMP hazardon the AESA radar is investigated,and some results about theneeded values for 10 percent of T/R units destruction arepresented.
