摘要
为了解决高重频脉冲多普勒末制导雷达制导过程中的距离遮挡和距离模糊问题,实现在距离遮挡环境下正常解模糊,提出了相应的解决方法:通过对发射信号重频进行参数设计,可实现在末制导过程中除弹目相遇段以外的任意距离段抗遮挡测距,再利用测得的弹目距离信息切换PRF实现抗遮挡。仿真证明了本方法的有效性和可靠性。发射信号重频的参数设计方法可有效使各脉冲重复频率信号的遮挡区交错分布,从而消除距离遮挡对于脉冲多普勒雷达解距离模糊的影响,准确的解模糊结果又为抗距离遮挡提供了有效保证。
Range ambiguity and eclipse are two inherent problems in HPRF PD terminal guiding radar. To solving the problems, a method is proposed. By designing the parameters of transmitting signal properly the range ambiguity can be resolved during the course of terminal guidance. Then the information of distance can be used to solve range eclipse problem by alterable PRF. The method is proved by simulation. The parameter design rule of transmitting signal makes the range eclipse area of each PRF interleaving redistribute. It effectively reduces the effect of range eclipse on resolving range ambiguity, and accurate distance information affords reliable assurance for anti-range eclipse.
