Phased array radar has been applied broadly because of its sound performance.But signal of phased array radar is of a wide variety of types.Therefore,recognition of phased array radar is the most puzzling aspect of the whole emitter identification domain.To solve the problem,the article proposes the method that identifies phased array radar by pulse amplitude information,and studies the phased array radar,models transmit signal of them,and receiving signal by radar countermeasure reconnaissance receiver.From constructing template of pulse train’s amplitude vector of mechanical scanning radar,computing distance of samples and standard template,finding threshold of the template matching arithmetic,the article puts forward the template matching algorithm of radar beam scan type recognition to identify phased array radar automatically.
Phased array radar has been applied broadly because of its sound performance. But signal of phased array radar is of a wide variety of types. Herefore, recognition of phased array radar is the most puzzling aspect of the whole emitter identification domain. To solve the problem , the article proposes the method that identifies phased array radar by pulse amplitude information, and studies the phased array radar, models transmit signal of them, and receiving signal by radar countermeasure reconnaissance receiver. Fv constructing template of pulse train’s amplitude vector of mechanical scanning radar , computing distance of samples and standard template, finding threshold of the template matching arithmetic, the article puts forward the template matching algorithm of radar beam scan type recognition to identify phased array radar automatically.
