Electro-Optical Design of Satellite Imaging Payload

Remote sensing using small spacecraft arising from multiobjective economic activity problems is getting more and more developed. These satellites require very accurate pointing to specific locations of interest, with high reliability and small latency. The space-borne imaging systems always attempted to achieve the highest ground resolution possible with the available technology at the given time. The most promising prospects for high resolution imaging with remote sensing satellites are connected with passive optical systems, especially pushbroom systems. In this paper optical system design process are described and deferent parameters of this process such as MTF, SNR, aperture diameter, stability and pointing, scanning schemes, detector selection, and target radiance are simulated and analyzed.
