摘　　要：拖曳式诱饵干扰严重威胁了单脉冲雷达制导体制地对空导弹的作战效能,介绍了当前导弹对抗拖曳式诱饵的研究情况,指出了现有导弹对抗拖曳式诱饵在制导律设计方面的局限性。在分析拖曳式诱饵干扰单脉冲雷达导引头测角原理和干扰特点的基础上,通过引入临界角将导弹—目标—诱饵相整合,动态分析了拖曳式诱饵对单脉冲雷达导引头测角的影响,并通过临界角将地空导弹攻击带拖曳式诱饵目标的制导过程分为临界角前后两个阶段,分析了侧向平面内导弹进入临界角时偏航角和侧滑角对命中目标的影响,为地空导弹抗拖曳式诱饵干扰制导律设计提供了新的思路和关键参数。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.
