A `pushbroom' sensor is an airborne imaging system which takes a series of one dimensional samples orthogonal to the aircraft line of flight with the second dimension constructed by the forward motion of the platform. With the advent of these highly sophisticated pushbroom reconnaissance sensors, system testing organizations are required to perform a detailed assessment of sensor performance. While in the past, systems have traditionally been tested using static or scrolling stimulation, such techniques have proven to yield only limited data. The Naval Air Warfare Center Aircraft Division, Patuxent River, Maryland has developed a ground test capability which supplies highly diverse and repeatable data and which provides a solid statistical base for the determination of system resolution. Working closely with the 3246 TW/DOR, Eglin Air Force Base, Florida, the exploitable nature of these data has been verified. This paper presents the data as actually taken from ground tests of a pushbroom sensor performed at Eglin Air Force Base and illustrates the methods and techniques employed to analyze and evaluate the resulting imagery.
