Photonic implementations of neural networks, which use electronics to furnish gain and implement neural transfer functions and establish weighted connections between neutrons using incoherent light, are discussed. Fully or partially optical implement

Data compression through a unitary transform is utilized in tomographic microwave diversity image reconstruction in order to reduce the dimensionality and to extract the features in the data space. The unitary compression is derived by minimizing the

The authors propose and describe a new concept in automated radar target identification from a single look (coherent broadband echo) based on neural net models. They view a neural net as a multidimensional nonlinear dynamic system capable of exhibiti

Microwave diversity imaging is used to study diaphanization by absorber covering. In this imaging system the absorber-covered object is illuminated by a plane wave and the backscattered field is received at a set of frequencies. The object is then ro

A novel method for microwave diversity radar imaging based on neural net models was developed. It is based on reconstructing a function f( theta , x, y), called the range-profile, which is a one-dimensional (1-D) Fourier transform of a single p-space

It is shown that in order to be truly cognitive a network must be nonlinear and dynamical and able to manifest bifurcation. This means it should be able to carry out phase-space computations with more than one type of attractor and to switch between
