A novel antenna consisting of a C band dual polarized waveguide slot antenna and an L band slot antenna with shared apertures is presented. The antenna meets the requirement of a dual band SAR application.
Filter bank-based methods for pixel classification are attractive due to the potential of fast implementation with convolution operations. The design of optimal filter sets, however, is a challenging task given the nonlinear aspects of the problem. This letter extends the well known linear discriminant analysis method into a novel framework for local texture feature discrimination tasks. It proposes...
In this paper, it is just doing a preliminary exploration to the multi-antenna array. The immune algorithm is used to achieve different directions for beam-forming and even pattern scanning. The array switches are loaded among the antenna arrays. The feed states and the switches among the arrays are controlled by using immune algorithm. Producing a particular orientation antenna pattern is regarded...
