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,MSPWVD-HOUGH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。
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 Parameters Estimation for radar echoes based on MSPWVD Hough Transform, Parameters used for motion compensation.
