Inverse Methods in Rough-Surface Scatteringrn power to the parameter of interest and minimize its sensitivity to other surface parameters. This is usually achieved by an appropriate choice of coherent or incoherent measurements, polarization, look angle and frequency..To invert for rms surface height, sensing wavelength should be large compa

On the Optimum Detection of Surface Chemical Compoundss of the different materials as they appear in nature. Surface roughness, local incidence angle variations, material mixtures, layers etc have to be considered to perform accurate measurements. Coherent optical scatterometry offers possibilities to improve the usefulness of existing reflection and s

Inversion Problems in SAR Imagingindirect measurements at a remote distance. Mathematically, the problem may be stated simply in one dimension as an attempt to solve an equation of the form . for the function F(x.), given a set of measurements of g(x) and some knowledge of the kernel function K(x, x.). A classical example is the de

Inverse Methods in Radio Glaciology principal observable in pulsed echo sounding was the echo-delay time and the inversion problem centred around the need to know both the velocity of propagation of electromagnetic waves in ice and snow and the position of the observation platform, accurately enough for depth sounding. The Antarctic

Fast Millimeter Wave Imaging the most important requirement of movement recognition and multiple target capability leads to very short times tolerable for collecting and processing the backscattered signals. High resolution with moderate aperture size requires short wavelength utilization. Hence, fast millimeter wave system sh

Electromagnetic Imaging of Dieletric Targets. Starting with the Born approximation, the observable quantities turn out to be simply related to the Fourier transform of the searched object-function and the same spatial frequency component may be obtained via different mapping configurations (“redundant measurements”). The exact scattering can
