| 摘 要： | 双星无源定位系统对地海面雷达辐射进行定位时,存在脉冲信号频差参数提取的模糊问题。提出了一种基于虚拟双星的双时差粗定位方法,可有效解决频差测量的模糊,再结合时差/频差联合定位方法,分析了双星系统对雷达辐射源无源定位的可行性,给出了一些有用的结论。

| Abstract: | For dual-satellites passive location system,there is severe frequency-delay of arrival(FDOA) estimated ambiguity when a ship-borne or ground-based radar target is been observed.A rough time-delay of arrival(TDOA) location method based on virtual baseline of dual-satellites system is presented to eliminate the frequency ambiguity.Then,the feasibility by using TDOA/FDOA jointed location algorithm is analyzed and some useful conclusion has been reached. |
