| 摘 要： | 小型无线电测量装置能够方便地同时测量功率及多普勒频率信息。通过研究基于功率和多普勒频率的目标运动分析算法,运用迭代最小二乘方法给出数值解。仿真实验显示,仅依靠功率信息,在低信噪比的情况下无法正确估计运动参数。而通过结合功率及多普勒频率信息能得到更准确的运动参数估计,适合于实际应用。

| Abstract: | The power and Doppler information from a radio emitter can be measured simultaneously by a smart radio device. It is more convenient in most TMA （target motion analysis） applications. This paper investigates TMA based on power and Doppler measurements. The numerical result is provided by an iterative least squares algorithm. |
