In this tutorial paper, remote imaging sensors such as airborne photography, infrared scanners, electro-optical sensors, television, and radar are discussed in terms of how their performance is affected by the aerospace vehicle in which they are carried. Imaging sensor performance is discussed in terms of such criteria as resolution, contrast rendition, dynamic range, signal- to-noise ratio, sensitivity, geometric fidelity, general appearance of results, reliability, and data usefulness. How the aerospace vehicle, carrying the sensor, affects the above criteria is discussed in terms of vehicle altitude or distance from target, temperature at the sensor, moisture at the sensor, induced and natural air turbulence around the vehicle, sensor window, and the various motions of the vehicle.
