Paper Abstract

Solid-state is a popular phrase today for its use indicates improvements in reliability and system efficacy. The purpose of this paper is to identify the systems engineering aspects of applying solid-state technology to earth observation applications that have traditionally been performed by point (or multiple-point) .detector line scanned mechanisms. The paper shows that the translation from a basically serial data flow point (or multiple-point) detector mechanically-scanned sensor to a solid-state highly parallel linear-array pushbroom sensor results in the minimization of mechanical complexity, but it maximizes electronics complexity, and for some applications, it also places increased demands upon optical performance. The paper discusses technical aspects indigenous to highly parallel photodiode linear array pushbroom applications. Examples of systems engineering applications are included. The applications are for a high resolution (10-m ground sample distance) narrow swathwidth (50 km), offset pointing sensor and a coarse resolution (80-m ground sample distance), wide swathwidth (185 km) sensor both operated in four bands from 0. 5 μm to 1.1 μm.
