| 摘 要： | 探讨了高分辨率雷达视频回波波形特征．提出对回波信号作Ｃｈｉｒｐ－ｚ变换，以提高频谱的分辨率．还对两类实测毫米波高分辨率雷达目标回波波形进行了Ｃｈｉｒｐ－ｚ变换及Ｆｏｕｒｉｅｒ变换，并对两类结果进行了比较，结果证明对雷达回波波形作Ｃｈｉｒｐ－ｚ变换获得的视频波形特征既满足同一目标特征稳定性，又容易区分两类不同目标．

| Abstract: | The video waveform feature of high resolution radar was discussed. Using the Chirp z transform, the extraction of high resolution waveform feature was presented. Two types of practical millimeter wave high resolution radar target waveforms were studied by Chirp z transform and Fourier transform. The results prove that by using the Chirp z transform the extraction of radar target video waveform feature can satisfy the stability principle of target feature and can easily recognize two different targets. |
