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.
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.
