    Seismic Waveform Inversion Using the Finite-Difference Contrast Source Inversion Method by Bo Han, Qinglong He, Yong Chen, Yixin Dou

    Published 2014-01-01
    “…This paper extends the finite-difference contrast source inversion method to reconstruct the mass density for two-dimensional elastic wave inversion in the framework of the full-waveform inversion. The contrast source inversion method is a nonlinear iterative method that alternatively reconstructs contrast sources and contrast function. …”

    Adaptive Radar Waveform Design Based on Weighted MI and the Difference of Two Mutual Information Metrics by Fengming Xin, Bin Wang, Shumin Li, Xin Song, Chi-Hsu Wang

    Published 2021-01-01
    “…Since DMI-based waveform does not allocate energy to the frequency band where the clutter power spectral density (PSD) is greater than the target PSD, we propose to weight the MI-based waveform and DMI-based waveform to synthesize the final optimal waveform. …”
