Description

technical field [0001] The invention belongs to the technical field of strong electromagnetic pulse protection, and in particular relates to a phased array radar strong electromagnetic pulse protective cover, which can be used for various L, S, and C frequency band phased array radars without affecting the normal operation of the radar. strong electromagnetic pulse protection. Background technique [0002] With the development of electromagnetic pulse technology, strong electromagnetic pulse weapon (including broadband ultra-wideband electromagnetic pulse and narrowband high-power microwave pulse) technology is gradually applied to equipment. At present, due to the super multi-target detection capability of phased array radar, phased array radar has become a major development trend of electronic information equipment. With the continuous enhancement of the detection capability of phased array radar, the sensitivity of phased array radar receiver is continuously improved, an...
