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.
The purely azimuth attack is an effective way for medium and long-range air-to-ship missiles to combat in complex electromagnetic environment. However, due to the lack of target distance information, the target indication and fire control solution are difficult to solve.Based on the analysis of azimuth quantization errors of airborne sensors , An optimization method of target parameter estimation based on azimuth velocity measurement of airborne sensors is proposed and the errors before and after optimization are analyzed and compared. The localization of the proposed optimization method is analyzed from two aspects: airborne passive radar and omnidirectional alarm The simulation results show that the localization error of this method is affected by both the target azimuth and the airborne sensor’s quantization error, and the error divergence region exists.On the basis of this, the strategy of mobile optimization of the aircraft with purely azimuth attack condition is proposed, Evade the positioning error divergence area and keep it as far as possible from the area.
