为了减少敌方进行电子对抗的机会,要求末制导雷达在保证一次捕获概率的同时尽可能减小角度搜索范围。针对在探测平台提供目标位置、航向和航速信息的条件下,目标散布满足椭圆误差模型的特点,提出了适应导弹自控点散布和目标散布的最小角度搜索范围模型,并对模型进行了详细分析和求解。在不同的雷达探测距离下,以高亚声速反舰导弹为例进行了仿真计算。结果表明,相比于只提供目标位置信息的目标散布圆误差模型,最小角度搜索范围可减小50%以上。
In order to reduce the enemy’s chance of electronic warfare, the terminal guidance radar is required to minimize the scope of the angle search while ensuring the probability of a capture. Aiming at the characteristics of the ellipse error model that the target scatters to satisfy the target position, heading and speed information provided by the exploration platform, a model of minimum angle search range that is suitable for the distribution and target scattering of missile self-control points is proposed. The model is analyzed in detail Solve. Under the different radar detection range, the simulation of high subsonic anti-ship missiles was carried out. The results show that the minimum angle search range can be reduced by more than 50% compared to the target scattering circular error model that only provides the target location information.
