In the modern electronic warfare,integrated jamming is one of the effective jamming methods to confront anti-ship missiles.Firstly,this paper introduces the shortage of only using active jamming or passive jamming;secondly introduces the integrated jamming method using active jamming and passive jamming:the effective reflected area of chaff centroid jamming rises by using active jamming equipments;thirdly,through calculation and analysis,validates the method is feasible;finally,illuminates that the method is effective through simulation assessment analysis.
