摘　　要：信息交链是防空反导作战中的关键技术。由于雷达特性的不同,需要雷达间协同工作,相互引导完成对弹道导弹的拦截,而提高预测精度能够为交班雷达提供高精度的速度与位置信息,从而快速准确地截获目标。从中段弹道出发,首先介绍了三种重要的坐标系;然后提出了一种新的弹道预测算法,最后对算法进行仿真。对比老式算法,证明其可行性和高精度性。Information chain is the key technology in the air and missile defense.The radars are supposed to work together and lead each other to achieve the interception of ballistic missiles,due to the different characteristics of the radars.Moreover,improving the prediction accuracy could provide speed and location information of high-accuracy for shift radars in order to intercept the target quickly and accurately.Starts from the middle trajectory,first three important coordinate systems,is introduced and then proposed a new trajectory prediction algorithm.Finally algorithm simulation,its feasibility and high accuracy compared to the old algorithm are proven.
