Abstract

Creation of millimeter wave range radiovision system with super-Rayleigh resolution is considered. On the base of phased antenna array (PAA) radiometer, methods of observed scenes scanning (survey) and output signals processing are developed to provide a vision with resolution on the order higher than Rayleigh level. Optimum mathematical methods (of type of reduction, deconvolution, decomposition) for processing of output signals of scanning radiometer are developed. Effective mathematical model of control by PAA pattern is built. Interconnection between sensitivity and resolution of radiometer measure-computer system with PAA is investigated, including the case of high level of noises. Algorithms of revealing of scenes elements with super-resolution are developed. As a result, created in 8-mm range measure-computer system with antenna array for environmental investigations provides 10- fold increasing of resolution of radiometer over Rayleigh level.
