The manipulation of the bands of a multispectral sensor for the simulation of a other band represents an attractive possibility for the handling of the data of remote sensing. This work presents a simulation technique for the MUX/CBERS-3. MUX (Multispectral Camera) is a Sino-Brazilian camera that is under development and will be launched on the platform CBERS-3. This study analyzes images generated with worse visual aspect taking in account the attributes of the sensors. Visual and statistics tests were accomplished to confirm the effectiveness of the methodology. The result of this processing is an image containing specific information, extracted and enhanced from the original images. The objective of this study is to propose a generic simulation method of spatial resolution based on the determination of the Modulation Transfer Function (MTF) by Zernike polynomials. The simulated images is important in all applications where is necessary work with images with different resolutions in order to compare the impact of change in terms of the visual analysis, resolution or performance of procedures for automatic image analysis. This research contributes to feasibility studies for future sensors, which is a very common practice to develop simulation procedures before of the construction of the sensor, where potential errors can be identified. This paper suggests a methodology for simulating band which consists of applying the techniques of filtering and resampling of images for the approximation of the desired spatial resolution.
