摘要 应用短时傅立叶变换、维格纳分布和Cohen类时频的分析方法分别模拟了一飞机目标的逆合成孔径雷达像,并对时频分辨率、交叉项的抑制能力和成像运算时间进行了比较,为逆合成孔径雷达成像中时频方法的选择提供了理论依据。 An ISAR Imaging of the plane target was respectively simulated based on several typical time-frequency analysis methods as short time Fourier transform,Wigner distribution and Cohen classes distribution.The time-frequency resolution,refraining ability of cross-term and imaging operation time had been compared that provides theoretical basis for the selection of time-frequency method in ISAR imaging.
