Radiometric targets for aerial photography

A network of approximately 200 targets ranging in diameter from less than 1 meter to nearly 3 meters. Spatial resolution targets at SSC consist of a 150-meter painted concrete radial target to estimate system spatial resolution and two 20x40-meter painted concrete edge targets to characterize edge response and estimate Modulation Transfer Function (MTF). The tour also included a first-hand look at a sample of SSC's 20x20-meter deployable radiometric tarps. The tarps, which are of four different reflectance values, support radiometric characterization as well as edge response characterization.
