Abstract: Owing to far working range,high transmission power and excellent anti-jamming characteristic,long-range surveillance radar is mostly used to searching and scouting air or maritime target,and could lead battleplane to execute mission,and comes under military countries' consieration and research.Project realiztion and literature writing is rarely obtained at OTH-econnaissance and jamming for long-range surveillance radar.This paper seeks for one new ground-to-ground jamming method by working over OTH-econnaissance and jamming.This method could disturb and damage the opposites' scouting our target,and secure our equipments,and moreover check up radars' anti-jamming capability.
