摘要
在我国的海洋目标侦察监视中,无人机定位技术具有灵活性好、定位范围大的优势,但在多无人机群协同定位方面,还存在着定位精度不高、动态规划航路的效率较低等问题。为提高无人机群的定位精度,提升远海区域的海上目标侦察和监视能力,研究了基于无源信号的时差频差数据的多无人机协同定位问题,并对算法进行了仿真和对比以及误差分析。最后,对多无人机协同定位侦察进行了展望。
In our country′s marine target reconnaissance and surveillance,UAV positioning technology has the advantages of good flexibility and large positioning range,but in the multi-UAV group coordinated positioning,there are still some problems,such as low positioning accuracy,low efficiency of dynamic route planning and so on.In order to improve the positioning accuracy of UAV fleet,effectively compensate for the blind areas of satellite and radar reconnaissance,and enhance the ability of target reconnaissance and surveillance at sea,this paper studies the cooperative positioning of multiple UAVs and dynamic route planning based on the results of time difference and frequency difference processing of passive signals,and simulates and verifies the model and error analysis.The prospects of cooperative positioning and reconnaissance of multiple UAVs are presented.
