提出了一种评估安防雷达性能的新方法。该方法利用搭载便携式高精度GPS (Global Positioning System)的无人机作为安防雷达被测目标,利用安防雷达实时录取该无人机目标数据,通过无线通信网络将便携式高精度GPS的定位数据从无人机回传至评估系统,经坐标变换将无人机定位GPS数据转换成以安防雷达为中心的极坐标数据,通过以太网接收雷达探测到的无人机目标数据,将无人机位置数据与安防雷达目标数据在评估系统终端上进行同步显示,再根据GJB 74—1998要求对探测威力、精度、发现概率等进行实时在线指标计算,满足对安防雷达的性能评估要求。 相似文献

The GPS satellite navigation system is capable of providing civil users with a horizontal positioning accuracy of 100 metres. As this is often inadequate for surveying or navigation, the differential GPS technique is used to improve positioning accuracy in a growing number of applications. The paper explains the differential GPS technique, outlines a typical differential GPS system and describes the procedure for computing position. In the latter part of the paper, the potential for the further development of differential GPS is reviewed and the applications described 相似文献

An outdoor navigation system using GPS and inertial platform 总被引:3,自引:0,他引:3
The use of global positioning system (GPS) in outdoor localization is quite a common solution in large environments where no other reference is available and there are not so demanding positioning requirements. Of course, fine motion without the use of an expensive differential device is not an easy task, even now that available precision has been greatly improved as the military encoding has been removed. In this paper we present a localization algorithm based on Kalman filtering that tries to fuse information coming from an inexpensive single GPS with inertial data and map-based data. The algorithm is able to produce an estimated configuration for the robot that can be successfully fed back in a navigation system. Some experiments show difficulties and possible solutions of this sensor fusion problem 相似文献

Currently, studies on autonomous driving are being actively conducted. Vehicle positioning techniques are very important in the autonomous driving area. Currently, the global positioning system (GPS) is the most widely used technology for vehicle positioning. Although technologies such as the inertial navigation system and vision are used in combination with GPS to enhance precision, there is a limitation in measuring the lane and position in shaded areas of GPS, like tunnels. To solve such problems, this paper presents the use of LED lighting for position estimation in GPS shadow areas. This paper presents simulations in the environment of three‐lane tunnels with LEDs of different color temperatures, and the results show that position estimation is possible by the analyzing chromaticity of LED lights. To improve the precision of positioning, a fuzzy logic system is added to the location function in the literature [1]. The experimental results showed that the average error was 0.0619 cm, and verify that the performance of developed position estimation system is viable compared with previous works. 相似文献
