Radiometric calibration (RC) is an essential solution to guarantee measurements from infrared photonic sensors with certain accuracy, the main task of which is to determine the radiometric responsivity of sensor and usually be solved by comparing with some radiation source (i.e., blackbody), called...
However, radiometric calibration methods in practice are difficult to implement for UAS remote sensing as every single image requires correction due to smaller field of view and changes in light. Therefore, this paper proposes an easy radiometric calibration process for UAS-based miniature multiple ...
2.2 Purpose of Calibration Targets The Mastcam-Z primary radiometric calibration target is a high-heritage (Fig. 1), evolution- ary development that combines design elements from camera calibration targets on the Mars Exploration Rovers (MER), Phoenix, and Mars Science Laboratory (MSL) missions. ...
Calculation of at-sensor spectral radiance is the fundamental step in converting image data from multiple sensors and platforms into a physically meaningful common radiometric scale. Radiometric calibration of the MSS, TM, ETM+, and ALI sensors involves rescaling the raw digital numbers (Q) transmitte...
