Abstract

Based on support of prior knowledge such as spectra database, using calculation for simulating radioactive transfer in time of remote sensing imaging, the invention obtains simulated remote sensing images in each range of spectral band of remote sensing images in high spectral resolution on basis of image texture information and field information provided remote sensing data in low spectral resolution. Moreover, the invention avoids difficult acceptant amount of calculation. Before satellite emission or on-board examination, the simulated images can be viewed so that it is useful for decision maker to select proper operating mode and parameter. The invention can also be used for researching mechanism of electromagnetic transmission in procedure for capturing remote sensing image.

Description

technical field [0001] The invention is a practical technology in the field of earth observation and a new optical remote sensing image simulation technology. The invention can provide required simulated images before satellite launch or airborne test, guide the selection of the working mode and parameters of remote sensing sensors; increase the perceptual knowledge of decision makers before sensor development and satellite launch; help to make up for the lack of remote sensing databases.
