Abstract

The invention discloses a method for generating a microwave spectrum hybrid image based on vegetation distribution. The method is characterized by comprising the steps of: acquiring remote sensing data and preprocessing the remote sensing data, wherein the remote sensing data comprises microwave remote sensing data and spectral remote sensing data; extracting a vegetation distribution region basedon the spectral remote sensing data; registering the microwave remote sensing data and the spectral remote sensing data, and extracting matched regions in the same range in the microwave remote sensing data based on the vegetation distribution region in the spectral remote sensing data; and generating the microwave spectrum hybrid image based on vegetation distribution. The method integrates theadvantages of microwave remote sensing and spectral remote sensing, overcomes the defect that features of land and plant distribution cannot be comprehensively characterized by using a remote sensingtechnology independently, improves the spatial resolution of microwave-spectrum hybrid pixels according to specific brightness temperature and distribution positions of vegetation, and can obtain high-spatial-resolution surface feature brightness temperature and vegetation distribution information.

Description

Technical field: [0001] The invention relates to the technical fields of geographic information system and remote sensing, in particular to a method for generating a microwave spectrum mixed image based on vegetation distribution. Background technique: [0002] Remote sensing technology, as the cutting-edge technology of earth information science, can continuously obtain large-scale ground information in a short period of time, realize rapid collection and quantitative analysis of vegetation information, respond quickly, and have strong objectivity. It is currently the most effective earth observation technology and information means of acquisition. [0003] The wavelength of microwave remote sensing in remote sensing technology is generally from 1cm-1m. Due to the longer wavelength, its energy can penetrate clouds, fog, sand and dust, and other atmospheric states except heavy rain. These advantages enable spaceborne passive microwave remote sensing to monitor the microwave...
