| 摘 要： | 针对海杂波背景下目标检测问题的实际需求,整理分析了STFT、WVD、PWVD和SPWVD 4种常见时频分析方法及其优缺点,并基于实测数据对海杂波的时频处理结果进行了对比分析。分别对纯海杂波单元和目标单元实测数据进行处理,将利用4种时频分析方法得到的结果进行对比、分析和总结。对4种方法在时频分辨率、目标能量积累程度、对海杂波抑制能力和平滑程度上各自特点进行分析,并总结得到相应的结论。

| Abstract: | In view of the actual requirements of target detection within sea clutter, four common time-frequency spectrumanalysis methods including STFT, WVD, PWVD and SPWVD were analyzed and their advantages and disadvantages werediscussed. The measured data of the sea clutter bin and the target bin was processed, and the results of the four time-fre?quency analysis methods were compared, analyzed and summarized. The performance of the four time-frequency spectrumanalysis methods in time-frequency resolution, target energy accumulation, sea clutter suppression and smoothness wereanalyzed and the corresponding conclusions were obtained. |
