| 摘 要： | 传统的时频分析方法,如Winger Ville Distribution,smoothed pseudo Wigner-Ville distribution等在多目标分辨的时候,无法同时在时频分辨率和抑制交叉项两方面同时达到较好的效果,所提出的MSPWVD解决了这一问题,MSPWVDHOUGH还可在低信噪比的情况下检测出多目标,并估算其参数,可利用来进行雷达成像的运动补偿.

| Abstract: | The traditional Time Frequency Distribution,Detection of unresolved targets based on Winger Ville Distribution,smoothed pseudo Wigner-Ville distribution,and so on,The proposed Mix pseudo Wigner-Ville distribution(MSPWVD) is better than the traditional Time Frequency Distribution.The SPWVD sacrifices time-frequency resolution in order to remove cross terms,but MSPWVD can not only reduce the cross terms but also maintain good time-frequency resolution.Detection of unresolved targets in the low SNR and Paramet... |
