A novel method that can identify moving status of birds accurately was proposed. The method can search the cross correlation coefficient of two neighboring high- resolution range profiles with advance-retreat method in spectrogram, based on the principal of generating micro-Doppler effects with the frequency-stepped chirp radar and characteristics of birds.
基于线性调频步进体制雷达微多普勒效应的产生原理,在距离一慢时间谱图上,针对鸟类目标特性,通过对精高分辨距离像进行分析,提出了一种利用进退法搜索相邻精高分辨距离像的互相关系数的方法来判别鸟类目标运动状态。

All above laid a foundation for the research of polarimetric information processing and application. Then, target optimum polarization and polarimetric synthesis technique were studied. By constraining polarimetric states of transmitting and receiving antennas, co-polarized and cross-polarized signatures were obtained. Because the received wave was partially polarized, completely polarized, completely unpolarized, and total available power signatures were defined based on the power of the return wave.
接着,论文深入研究了目标最佳极化和极化合成技术,通过约束收发天线的极化状态可以得到共极化特征图和交叉极化特征图,由于雷达接收的电磁波通常是部分极化的,根据接收波的平均功率密度可以得到未极化特征图、完全极化特征图和匹配极化特征图,在极化特征图空间中搜索可以很容易地获得目标的最佳极化,这些目标最佳极化可以作为极化目标识别和分类的极化特征。
