摘要
本文给出不同电尺寸下雷达散射截面积的幅值变化曲线;分析目标散射特性的计算方法,并给出雷达散射截面积随频率变化的曲线;探究多频极点的目标识别方法,并且通过最小描述长度法确定目标极点数,同时通过Prony法对目标极点进行求解;最后对高频雷达目标识别进行仿真,给出正确识别率和拒判率随信噪比的变化曲线。
This article provides the amplitude variation curves of the radar scattering cross-sectional area under different electrical sizes.Analyzed the calculation method of target scattering characteristics.Explored the target recognition method for multi frequency poles,provided the target impact response curve,and determined the number of target poles using the minimum description length method.At the same time,solved the target poles using the Prony method.Finally,simulation was conducted on high-frequency radar target recognition,and the variation curves of correct recognition rate and rejection with signal-to-noise ratio were provided.
