摘要
针对无源定位中的时差频差联合估计问题，在利用互模糊函数进行时差频差估计的基础上提出了具体工程实现时运算量较小的方案，并针对不同调制样式在不同带宽和灵敏度条件下进行了仿真，通过仿真结果总结出提高时差频差测量精度的途径。
Aimed at the joint TDOA-FDOA estimation issue in passive location, based on the joint TDOA-FDOA estimation algorithm by using the cross ambiguity function, a solution with less computation in the engineering implement is brought forward. Simulation aimed at different modulations in different bandwidth and sensitivity is done. Approaches to enhance the TDOA- FDOA measure precision are summarized based on the simulation result.
