摘要
为了实现机载探测器对地面目标稳定、快速和实时的测距,提出了一种新颖的利用频域和时域信息的机载无源测距方法,详细分析了测距算法的基本原理,并对测距算法的误差和可观测性进行了研究,计算机仿真结果表明,这是一种有效实用的好方法。
In order to realize fast and stable and real time passive ranging for airborne detector to ground target,one novel airborne passive ranging method is presented which adopted frequency range and temporal information. The analysis of basic principle of the ranging algorithm is discussed. Research on the ranging error and observability of the method is presented. The computer simulation results indicate that it is a good effective method.
