基于时频分布的跳频信号分析研究，短时傅立叶变换，魏格纳分布，伪魏格纳分布，平滑伪魏格纳分布(Based on the distribution of time-frequency analysis of frequency hopping signals, short-time Fourier transform, Wigner distribution, pseudo-Wigner distribution, smoothed pseudo-Wigner distribution)

We consider a complex-valued wavefield reconstruction in an object plane from data in a sensor plane. A digital modeling for the forward propagation is presented in the algebraic matrix form M-DDT. The inverse propagation is formalized as an inverse problem. The main algorithm of the complex-valued wavefield reconstruction with the proposed Matrix Discrete Diffraction Transform (M-DDT) is prepared as a Matlab demo.
