摘要
针对临近空间高超声速目标航迹起始困难的问题,依据超视距雷达能够提供目标精确多普勒信息的特点,从径向速度、径向机动能力和角速度3个方面推导了航迹起始约束条件,文中给出了更为精确的相关波门设计方法,通过目标运动特性确定最终航迹。仿真结果表明,该方法能够有效起始临近空间高超声速目标航迹,且效果优于传统利用目标位置信息进行航迹起始的方法。
Aimed at the problem that it is hard to initiate the near space hypersonic target track, according to characteristics which the over-the-horizon radar can provide the precise target Doppler information, the traek initiation constraints are derived from three aspects of the radial velocity, radial mobility and angular velocity and the more accurate wave gate design methods are given, the final flight paths are determined by target motion characteristics. The simulation results show that this method can effectively start near space hypersonic target track, and the results are superior to the traditional target location information for track initiation.
