EXTRACTION OF RADAR TARGET WAVEFORM FEATURE USING CHIRP Z TRANSFORM
用Chirp—z变换获得雷达目标回波波形特征

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.
