摘要
基于时频差的无源定位体制具有精度高、可瞬时定位的特点,得到广泛研究和应用。在不同定位场景下各类时频差定位算法性能不尽相同,为在更真实环境下仿真验证算法性能,设计了时频差定位半实物仿真平台,构建平台硬件系统并进行平台软件开发。通过对不同仿真场景的试验分析,验证了该半实物仿真平台适用性,可对时频差定位算法性能指标进行仿真验证。
Passive localization system based on TDOA/FDOA has the characteristics of high accuracy and in-stant localization,so it is widely researched and applied.The performance of various TDOA/FDOA localization algorithms in different scenarios is not the same.In order to simulate and venify the performance of the algo-rithm in a more realistic environment,this paper designs a Hardware-in-the-loop simulation platform for TDOA/FDOA localization,and builds platform hardware system and develops software.The applicability of the platform is verified through experimental analysis of different simulation scenarios,and the performance indica-tors of TDOA/FDOA localization algorithms can be simulated and verifed.
