空舰导弹纯方位攻击目标指示优化方法

纯方位攻击是中远程空舰导弹适应复杂电磁环境下作战的有效途径,但由于目标距离信息缺失,其目标指示和火控解算问题难以解决.在分析机载传感器方位角量化误差的基础上,提出了基于机载传感器方位角速度测量的目标参数优化估计方法,对优化前后的误差进行了分析和对比;从机载无源雷达和全向告警器两个途径分析了所提出优化方法的定位精度分布情况.仿真结果表明:该方法的定位误差受目标方位与机载传感器量化误差的共同影响,存在误差发散区域.在此基础上,提出纯方位攻击条件下载机机动优化的策略是对目标定位误差发散区域进行规避,并尽可能远离该区域.

Optimization of target designation for air-ship missile under condition of bearing-only attack

Bearing-only attack is one of the most effective approach for air-ship missiles to adapt complex electromagnetic combat environment. Because of the absence of target distance information, the target designation and the fire control parameters are hard to be solved. Based on the analysis of quantization error of airborne sensors, the optimized estimation method of target parameters based on the measurement of target rotation speed by the airborne sensors was proposed. The error of the original and optimized estimation method was analyzed and compared. The distribution of locating precision in polar coordinates of the proposed method was simulated by the approaches of airborne passive radar and omnibearing warning system. The simulation shows that there are error divergence domains determined by the orientation of target and the quantization error of airborne sensors. Further more, the optimized maneuver strategy of battleplanes under the condition of bearing-only attack was proposed, which suggests that battleplanes be out of the divergence domains, and be away from these domains as far as possible.
