| 摘 要： | 为了对被动雷达导引头的抗干扰性能进行评估,利用功率准则。首先根据二次雷达方程推导过程中,雷达接收到单程传播信号的功率公式,得到被动雷达导引头接收机输入端的信号功率公式。然后在此基础上分别推导出只存在理想噪声和只存在有源噪声干扰情况下被动雷达导引头的作用距离。最后推导出被动雷达导引头的相对烧穿距离公式。利用该公式对目前几种典型的反辐射导弹导引头的抗干扰能力进行了评估。评估结果说明该方法是一种准确有效的评估方法,能够客观反映被动雷达导引头的抗干扰能力。

| Abstract: | In order to evaluate the anti-jamming capability of PRS, the input signal power equation of PRS is derived according to the second radar equation using power rule. Then working range of PRS is given both under ideal noise and noise jamming circumstances on the base of that. And finally relative burn through range is derived out, anti-jamming capabilities of several ARM seekers is estimated using that equation. Result shows that it is an effective and accurate evaluation method and that it can reflect anti-jamming capability of PRS objectively. |
