One of effective directions of increase информативности active and passive systems of remote supervision is multidimensional spatially-time-and-frequency sounding. In maintenance of development of this direction systems with posterior processing of results of measurements (SPPRM) and new continuous models of signals with which use various problems of an estimation of functional properties and information possibilities of systems of type SPPRM are solved are offered. At the same time offered in model of signals do not consider power characteristics of accepted signals (easing on a distribution way), and also characteristics of objects of supervision (for example, value of an effective surface of dispersion) that complicates reception of quantitative estimations of power characteristics of systems of type SPPRM (energy of accepted signals, the relation a signal/noise etc.), making essential impact on quality of the decision of information problems. The purpose of present article is working out of models of signals in systems of supervision with joint апостериорной processing of results of the multichannel measurements considering power characteristics of objects, supervision systems, and also easing of electromagnetic waves and their use for calculation of power characteristics of systems of various types. In article power models of signals in various systems of supervision of type SPPRM which are offered consider effective surface of dispersion object of supervision, the characteristic of reception and transferring aerials, procedure of reception of results of primary measurements, and also easing of signals in the course of distribution of radio-waves. Expressions for an estimation of energy of a signal in systems of supervision of type SPPRM with any form and structure of reception and transferring aerials generally and in case of scanning combined reception and transferring elements are resulted.
