基于TDOA的弹箭残骸轨迹定位监测技术研究
Research on Trajectory Monitoring Technology of Missile and Rocket Wreckage Based on TDOA
摘要
Abstract
The accurate location and continuous monitoring of missile and rocket wreckage is one of the key technologies to realize the recovery of missile and rocket wreckage.According to the characteristics of the flight trajectory of the missile and rocket wreckage,based on the multi-station time difference of arrival passive positioning principle,a technical solution for trajectory monitoring of the missile and rocket wreckage is designed.According to the time difference information of the missile and rocket wreckage active radiation signals received by multiple base stations,the Chan algorithm is used to locate the position of the missile and rocket wreckage for continuous monitoring of the wreckage trajectory.The feasibility of the technical scheme for trajectory monitoring of missile and rocket wreckage is verified by simulation using flight trajectory data of the rocket recovery cabin.The influence of base station distance and base station configuration on trajectory monitoring effect of missile and rocket wreckage cabin section is analyzed through positioning accuracy comparison test.The calculation results show that:in the square configuration,the greater the distance between the base stations,the higher the positioning accuracy;among the three configurations of diamond,Y-shaped and square,the diamond configuration has the best positioning accuracy.关键词
