		<abstract>The production of images, with radiometric and geometric quality suitable for various applications in the area of remote sensing, depends directly on the performance of the sensors on board satellites. Among the various existing parameters, the Signal/Noise Ratio in the satellite images is an important indicator for the assessment of data quality and performance of satellite sensors throughout its operational life. Methods for analyzing the Signal/Noise Ratio established by the scientific community have been described pointing their advantages and disadvantages as well as the performance of each method based on his theories. In this work we were estimated relations Signal/Noise using the Local Variance Method using samples taken from homogeneous areas of the following sensors: OLI Landsat-8 satellite and MUX / WFI / PAN CBERS-4 satellite. The results obtained in the experiments responded to this proposed work, which was to assess whether the results were within the sensor specifications, and the Local Variance Method is effective, easy to apply and with a certain reliability of its results.</abstract>
