Paper Abstract

By the use of statistical decision theory and space-and-time correlation function of coherent field, scattered by moving rough object, probability density function (PDF) of these fields in the presence of additional background fields is deduced. The PDF is used as an information capacity measure of random coherent field, scattered by moving object, so it enables development of an algorithm for processing the coherent field scattered by the object with an arbitrary surface shape and motion parameters during the observation time of the scattered field. This algorithm requires forming the coherent image of the moving object and taking the Fourier-Fresnel transform of the field in each point of this image. The algorithm can be used for determining the dynamic parameters and shape of moving objects even if the imaging system has very low resolution.
