基于双谱分析的毫米波多普勒引信目标检测

目标检测是毫米波多普勒引信信号处理的重要内容，在目标检测过程中，传统功率谱等技术不能充分揭示隐含于目标回波中的高阶统计信息，不能消除噪声和杂波的影响，不利于目标特征分析及检测，因此提出了基于双谱分析的毫米波多普勒引信目标检测技术，利用双谱及双谱对角切片进行特征分析及优化，通过对实测毫米波多普勒引信数据进行理论分析和试验仿真，结果表明采用双谱分析的毫米波多普勒引信目标检测方法有效可行。

Target Detection Technique of MMW Doppler Fuze Based on Bispectrum Analysis

Target detection is an important study content of MMW Doppler fuze signal processing, power spectrum technique in tradition can not only open out the high-step statistical information of MMW targets echo signal but also eliminate the effect of the noise signal and clutter. And in this way the characteristics of target are hard to be analyzed and detected. So the target detection technique of MMW Doppler fuze based on bispectrum analysis is brought forward. The bispectrum and diagonal slicing of bispectrum are analyzed and optimized. And by analyzing and simulating the dates of MMW Doppler fuze in practice measurement, it＇s clear that the method of target detection for MMW Doppler fuze signal based on bispectrum analysis is feasible.
