Analysis of High Intensity Electromagnetic Pulse Protection for Ground Radar System

On the basis of brief introduction of non-nuclear electromagnetic pulse directed-energy weapons development, the variation of radiation power of space-based non-nuclear high intensity electromagnetic pulse source with distance is analyzed. The corresponding radiation intensity may cause different effects of interference, degradation, hurt or even damage to sensitive parts of the radar system. Analyzing and calculating the power levels of different intensity space radiation fields coupled into the radar antenna system. By comparing and analyzing the high intensity electromagnetic environment assessment data provided by US military standard, the level of protection is proposed. On this basis, the front and rear door coupling ways and possible damage effects of high intensity electromagnetic pulse entering the ground radar system are analyzed. Aiming at different coupling paths, the corresponding protective measures are analyzed. It provides a reference for the strengthening of high intensity electromagnetic pulse protection and technical application of information equipment.
