Abstract:	Towed decoy interference seriously threatens the combat effectiveness of monopulse radar guidance system surface to air missile.This paper introduces the current research direction of missile against towed decoy and points out the existing limitations of against towed decoy missile guidance law. On the basis of analyzing the principle and interference characteristics of towed decoys interfering with the angle measurement of single pulse radar guide head, the influence of towed decoys on the angle measurement of single pulse radar guide head is dynamically analyzed by introducing the critical angle to integrate the missile target decoy phase, and the influence of towed decoys on the angle measurement of single pulse radar guide head is dynamically analyzed.In addition, through the criticalangle, the guidance process of a surface to air missile attacking a target with a towed decoy is divided into two phases (before and after the critical angle), and the effects of the yaw angle and sideslip angle on hitting the target when the missile enters the critical angle in the lateral plane are analyzed.This paper provides a new idea and key parameters for the guidance law design of surface to air missile against towed decoy interference.
