The application of the extend prony method in enhancement the resolution of SFCWGPR

本文研究了ExtendProny方法在提高步进扫频探地雷达分辨率、提取目标距离信息中的应用.结合扫频雷达回波信号的特点,对Prony算法处理步骤和改进措施进行了重点阐述,并利用实测数据对算法有效性进行检验,对不同探测目标、有无噪声干扰情况下算法的鲁棒性给出评价.最后对该算法在目标自动识别中的应用潜力给予了说明.

This paper investigates the use of Extend Prony Method for range extraction and enhancement resolution in a SFCW Ground Penetarting Radar.Then,the procedures of Prony Method and several key improvements to the algorithm, including the use of SVD and the removal spurious clutters are presented.The algorithm＇s robustness and performance in the presence of noise are tested by processing experimental datas. At last, the paper reveals the potential use of the Extend Prony Method in automatic target recognition.
