Informational capabilities of microwave and optical tools for environmental monitoring are assessed when they are located on the mobile platforms. This paper presents new approach to the combined use of microwave and optical sensors as basic elements of environmental monitoring system architecture oriented on the registration of information about characteristics of hydrological and hydrochemical objects. Geoecological in-formation-modeling system (GIMS) is proposed as the GIS generalization with regard to the solution of series of the tasks arising in the agriculture, water quality assessment and operational diagnostics of stressful natural processes. Algorithms and models are characterized to be as the GIMS components that realize the decision making procedures providing the monitoring regime optimization and reconstruction of spatial image of the controlled environmental object using anisotropic data fluxes. Functional characteristics of several mobile platforms equipped by microwave radiometers are given as tools for the monitoring of hydrological objects. Two optical instruments are represented and their functions are characterized.

“…The spectrophotometer measures the spectral curve S(λ), and the spectroellipsometer measures the spectral curves S Ψ (λ) and S ∆ (λ), respectively. Optical diagnostics of water systems is carried out directly by analyzing spectral curves using specific algorithms and models [8,9,11,[14][15][16][17] .…”

Multi-channel polarization optical technology is increasingly used for prompt monitoring of water systems. Optical devices during the assessment of water quality determine the intensity of light through the studied aquatic environment. Spectrophotometric devices measure the spectrum of weakening of light through the aquatic environment. Spectroellipsometric devices receive spectra in vertical and horizontal polarizations. The presented article develops an adaptive optical hardware and image system for monitoring water bodies. The system is combined. It consists of 2 parts: 1) automated spectrophotometer-refractometer, and 2) adaptive spectroellipsometer. The system is equipped with a corresponding algorithmic and software, including algorithms for identifying spectral curves, databases and knowledge of spectral curves algorithms for solving reverse problems. The presented system is original since it differs from modern foreign systems by a new method of spectrophotometric and spectroellipsometric measurements, an original elemental base of polarization optics and a comprehensive mathematical approach to assessing the quality of a water body. There are no rotating polarization elements in the system. Therefore, this makes it possible to increase the signal-to-noise ratio and, as a result, improve measurement stability and simplify multichannel spectrophotometers and spectroellipsometers. The proposed system can be used in various water systems where it is necessary to assess water quality or identify the presence of a certain set of chemical elements.
