定向战斗部要求具有能够识别目标方位的定向探测引信,因此,提出了一种能够识别弹体周向四个方向的定向探测方法;通过一个单刀四掷PIN开关控制分布在弹体周向的四个微带天线进行电扫描,当某一方向有目标出现时,即可通过反射回来的微波信号判定目标方位。介绍了该探测器的工作原理;给出了探测器的总体方框图;阐述了探测器各部分的原理及功能;详细介绍了定向探测天线的设计方法;并对电扫描过程中要考虑的因素等进行了分析。
Directional warheads are required to have a directional detection fuze that can identify the target azimuth. Therefore, a directional detection method that can identify the four directions of the missile body is proposed. A single-pole four-throw PIN switch controls the four A microstrip antenna for electrical scanning, when a target has a direction, you can determine the target by reflecting the microwave signal. The working principle of the detector is introduced. The overall block diagram of the detector is given. The principle and function of each part of the detector are expounded. The design method of the directional probe antenna is introduced in detail. Analyzed.
