基于脉冲相关技术的反辐射导弹检测

Detection for Anti - Radiation Missile Based on Pulse Correlation Technique

以反辐射导弹告警系统为背景,根据典型反辐射导弹的发射模式,建立了反辐射导弹的雷达回波时间序列模型,指出了告警系统对反辐射导弹的脉冲串检测实际上是速度及加速度分量未知的线性调频信号的检测。以该模型为基础,提出了用脉冲相关技术来完成反辐射导弹的检测,对该方法的检测性能进行了分析,并研究了机弹分离时该方法的应用情况,为在工程上完成反辐射导弹回波脉冲串的检测提供了理论基础。

In this paper, based on the alarm system of ami - radiation missile and the launch pattern of ami - radiation missile, time series models of anti - radiation missile are bulit, and it is pointed out that alarm system finishing the detection of pulse series is actually the detection of linear frequency modulation with unknown velocity and acceleration components. The paper presents a method named pulse correlation technique finishing the detection of anti - radiation missile, the detection performance of this method is analyzed, and how to apply this method to the situation of separation between aircraft and missile is also studied, all these analysis offer the theoretical basis for the detection for anti - radiation missile.
