| 摘要: |
| 谱分析是雷达信号处理的重要组成部分, 对目标分类、特征检测均有重要意义。高阶谱所具有的特殊性质, 有助于人们从新的角度对雷达回波进行分析。本文提出了一种双谱分析双(Q，K) 方法。仿真结果表明, 本文提出的方法与其它的双谱估计算法相比估计精度更高。最后给出了应用实例。 |

| Abstract: |
| Spectrum analysis is the most important branch in radar signal processing and significant of radar target classification and feature detection. Having the special property, higher spectrum is very useful for us to analyse radar echoes from a new view. This paper presents double (Q, K) bispectrum algorithm for ultra-wideband radar echoes. Compared with other bispectrum estimation algorithm, simulation results show that the algorithm we presented here has significant improvement. At last, we cite an example for the application. |
