Due to the effect of transmitting current turn-off time, transient process of receiver coil and long sampling interval, the transient electromagnetic method fails in resolving the shallow target in the vertical direction. A numerical method calculating the all-time apparent resistivity for transient electromagnetic method was proposed, which could be applied to calculate apparent resistivity with...
In this letter, a texture-preserving despeckling algorithm for synthetic aperture radar images using an evidence framework is proposed. The salient aspects of this approach are given as follows. (1) The maximum a posteriori estimate can be guaranteed to converge to the optima by selecting the Gaussian distribution and Gaussian Markov random field model as the likelihood function and prior model, respectively...
