Abstract

The high power electromagnetic pulse (EMP) with sufficient radiating energy can penetrate and interfere on all kinds of radars. This paper studies the interference effect of high power EMP on paraboloid radar and AESA radar respectively. The coupling EMP (5us duration) energy via main lobe and side lobe into a paraboloid radar antenna is calculated. The distance and other parameters at which the sensitive component 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 side lobe is studied and modeled. Finally, high power EMP hazard on the AESA radar is investigated, and some results about the needed values for 10 percent of T/R units destruction are presented.
