摘要
在单站无源定位与跟踪系统中,获取雷达脉冲信号的高精度频率信息是一个关键技术.本文研究了噪声干扰下的相参脉冲信号频率提取问题,提出了一种新的频率估计方法.该方法具有精度高、运算量小的优点,计算机仿真实验证明了方法的有效性.
The acquisition of accurate frequency out of the complex radar pulse signal is a key technology in the passive locating and tracking system of single site. The frequency extraction of the coherent pulse signal in additive noise was studied, and a new algorithm was proposed for the frequency estimation. By simulation, it is shown that this algorithm has higher estimating precision and lower computation, which is very effective.
