为了提高导弹在攻击过程中的生存概率,需要合理地进行弹道设计。本文以锥球体作为弹头模型,基于单脉冲体制雷达,运用电磁计算软件计算弹头的RCS值,并对弹头在不同射面角和不同的垂直高度下的被检测概率进行了计算。结果表明:检测概率较高有两个区域,分别为射面角在0°~90°、弹头垂直高度为20km~60km和射面角在270°~360°、弹头垂直高度为20km~60km的区域。在射面角为90°~270°,弹头的检测概率一直处于较低的水平。所以可以通过合理选择导弹的射面角来改变雷达视角,从而使弹头的被检测概率处于一个较低水平。
In order to improve the survival probability of the missile during the attack, it is necessary to carry out ballistic design reasonably. In this paper, the cone sphere is used as the warhead model. Based on the single pulse radar system, the RCS of the warhead is calculated by using the electromagnetic calculation software. The probability of the warhead being tested at different shot angles and different vertical altitudes is calculated. The results show that there are two regions with higher detection probability, ranging from 0 ° to 90 ° for shooting angle, 20km-60km for vertical warhead and 270 °-360 ° for vertical warhead, and 20km-60km for warhead area. In the surface angle of 90 ° ~ 270 °, the detection probability of warheads has been at a low level. Therefore, we can change the angle of view of the radar by reasonably choosing the surface angle of the missile so that the probability of detection of the warhead is at a low level.
