简介:本文介绍了高空防御导弹雷达制导系统设计中的有关问题:讨论影响系统脱靶量的三种重要因素——导引头回波信号的纯净、导引头分系统的非完善性和导弹响应的局限性.在高空,目标角闪烁是沾污导引头回波信号的主要因素.另外,导引头的非完善性,例如天线平台的稳定性,天线罩的折射效应以及陀螺加速度灵敏度等,都会产生不稳定性和脱靶问题.再则,由于降低了导弹的加速度能力,增加响应时间和舵面速度的饱和,导弹对控制指令的响应也会受影响.本文针对上述情况进行讨论.希望通过实际例子来说明在系统设计的初步阶段,这些问题就应引起设计者的重视.
Summary: This article describes the design of high altitude defense missile radar guidance system issues: discuss the impact of system miss distance of the three important factors - seeker echo signal purity, imperfect seeker subsystem and missile response At high altitudes, the flickering of the target angle is a major factor contaminating the seeker’s echo signal.In addition, the imperfection of the seeker, such as the stability of the antenna platform, the radiative effect of the radome and gyroscopic acceleration sensitivity , Both instability and off-target problems arise.In addition, the missile’s response to the control commands will also be affected due to the reduced ability of the missile’s acceleration, increased response time and saturation of the rudder speed. The actual example shows that in the initial stage of system design, these problems should draw the designer’s attention.
