| 摘 要： | 提出了通过空域中多架载机对同一目标的测量信息进行目标定位的一种多机协同机载无源定位系统。多机协同的无源定位系统能够克服单基定位系统基线短的缺点,利用多载机之间的长基线能够实现目标的高精度定位。给出了单/多基体制下不同定位方法的基本原理,并进行了对应算法的几何稀释精度定位和响应时间的仿真分析。通过仿真结果发现,在定位精度要求相同的情况下,该系统的响应速度能够提高十倍以上。

| Abstract: | A multi-static cooperative airboren passive location system is proposed in this paper. This system can locate the target by locating the measured in formation of the same target in the airspace. The system can overcome the shortcoming of short baseline of single static, and realize high-precision location. The GDOP positioning precision and the response time of different positioning methods of the single-/multi-static systems are analyzed. The simulation results show that the response speed of the system can be increased by more than ten times. |
