| 摘 要： | 针对地面单站低频雷达及多站协同时差测量系统的缺点,提出了一种有源三动平台空中分布式协同时差测量系统。给出了空中分布式协同时差测量系统的目标定位方法,建立了定位及交班误差分析模型,对精度和测量条件等进行了研究。最后,通过仿真验证了其相对于单站雷达的精度。该系统在实现远距离隐身目标高精度定位的同时,可大大降低系统对地面及动平台末制导探测设备的要求。

| Abstract: | To consider the shortcomings of ground single low frequency radar and distributed coordinated time difference measurement system, an active three moving platforms air distributed coordinated time difference measurement system is presented. The target location method and error analysis models are given. The precision measurement conditions are researched. Finally, the precisions relative to single radar are confirmed by means of simulation. Based on the system, the high target location precision can be realized, especially to stealth targets. At the same time, the requirement of ground and moving platform terminal guidance detection equipment can be reduced. |
