| 摘 要： | 在对雷达通道均衡的实验研究中发现,常用的基于傅里叶变换的算法往往效果不佳。原因是该算法获得的均衡器无法实现非最小相位。提出了一种雷达通道均衡算法,该算法通过对需要均衡的通道输出进行延迟,实现了可以获得非最小相位特性的基于傅里叶变换的均衡算法。通过仿真和实验,对该算法的性能进行了验证。结果表明,与原算法相比,新算法可以获得更好的幅度和相位一致性。

| Abstract: | Unsatisfied results are often achieved when using the algorithm based on Fourier transformation in radar channel equalization experiment. The reason is that the equalizer cannot realize nonminimum phase. Nonminimum phase equalization algorithm based on Fourier transformation is proposed in this paper via delaying the data of the being equalized channel. Its performance is tested by computer simulation and experiment data, and the results show that better magnitude and phase consistance is achieved compared to the original algorithm. [ |
