in this paper, the detector of moving target in mimo radar with widely separated antenna in the presence of α-stable clutter is proposed. due to the complexity of unknown parameter estimation in the presence of target, the rao test is applied. the α-stable model is a general model that can applied to different environments with appropriate selection of parameters. the problem with this model is...

We present the Iwasawa decomposition theorem for the group Sp (2, R) in a form particularly suited to firstorder optics, and we exploit it to develop a uniform description of the shape-invariant propagation of several families of optical beams. Both coherent and partially coherent beams are considered. We analyze the Hermite–Gaussian beam as an example of the fully coherent case. For the partia...

In an absorbing medium, where the vector W5]v/]k usually is complex for real values of the wave vector k, the group velocity W may become real for some complex values of k. The role of real group velocity in the propagation of one-dimensional wave packets in homogeneous absorbing media is examined. Applying the saddle point method to an analysis of the asymptotic behavior of the Gaussian wave p...
