In microwave radiometry for early detection of breast malignancy a contacting antenna is scanned on the breast surface, while a pressure is exercised along with a deformation. Assuming the antenna at lower temperature than the breast, the results of a numerical modeling show an interesting increase in tumor radiometric visibility in compressed breast. Preliminary results on a real radiometric a...

The upcoming Fluorescence Explorer (FLEX) satellite mission aims to provide high quality radiometric measurements for subsequent retrieval of sun-induced chlorophyll fluorescence (SIF). combination SIF with other observations stemming from the FLEX/Sentinel-3 tandem holds potential assess complex ecosystem processes. calibration and validation (cal/val) these derived products are central but ch...

Nonuniform exposures often affect imaging systems, e.g., owing to vignetting. Moreover, the sensor's radiometric response may be nonlinear. These characteristics hinder photometric measurements. They are particularly annoying in image mosaicking, in which images are stitched to enhance the field of view. Mosaics suffer from seams stemming from radiometric inconsistencies between raw images. Pri...

The moon is a very stable reference source that has been used for the space-borne sensors’ radiometric calibration and/or radiometric stability monitoring. In this paper, we present an approach that uses the sensors’ on-orbit lunar observations for their spatial characterization and apply the method to the MODIS instruments that are currently operating onboard NASA EOS Terra and Aqua satellites...

Hyperspectral remote sensing is used in precision agriculture to remotely and quickly acquire crop phenotype information. This paper describes the generation of a digital orthophoto map (DOM) and radiometric calibration for images taken by a miniaturized snapshot hyperspectral camera mounted on a lightweight unmanned aerial vehicle (UAV). The snapshot camera is a relatively new type of hyperspe...

The orthophoto is a powerful instrument of representation which combines radiometric and geometric properties. In architectural applications the orthophoto production cannot be performed by using the traditional orthophoto approach. True digital orthophoto is a new technique which uses several images and a complete DEM of the object in order to produce an orthogonal projection of complex object...

Full-waveform laser scanning extends the information content of “conventional” laser scanning by storing the temporal profile of both the emitted laser pulse and its echoes. This allows for calculating radiometric quantities in addition to the geometric data. This radiometric information needs to be calibrated in order to enable comparison among flight strips of the same laser scanner campaign ...
