A Novel Approach of Countering Centroid Jamming By Using INS Information in Terminal Guidance

摘要：

During anti-ship missile (ASM) tracking ship in terminal guidance phase, echo in monopulse radar seeker receiver was generated by modeling chaff and ship as Swerling II and Swerling IV in chaff centroid jamming scenario, respectively. A generalized likelihood ratio test (GLRT) algorithm was then proposed for chaff detection in the main-beam. When the presence of the jamming was detected, one can combine target position forecast with inertial navigation system (INS) navigation solution to accomplish the homing guidance of ASM, and then when the absence of the jamming was detected, radar seeker capture and track target again, which could help achieve ones purpose of anti-jamming. Simulation showed that this method was effective and feasible due to its preferable anti-jamming performance.
