Multispectral Radiometry for the Determination of the Vegetation Cover Conditions

This paper deals with the possibility of multispectral radiometry using to determine local conditions of plants including inverse problems in localization and decomposition of measured data into the physical parameters - e.g. emissivity (noise temperature) into the "temperature" and "water contents". The possibility of the study of vegetation cover is interesting due to the different properties of water in microwave, mm and submillimeter regions. In order to retrieve information from measurement the following steps are to be done: - antenna pattern deconvolution, - apparent emissivity interpretation (decomposition). Applications could be possible in agriculture for the depression of the using of the protective chemical materials. Early and local determination of plants illness could be very attractive applications but there are also many experimental difficulties.
