Abstract
The primary objective of this study is to assess the potential military utility of a limited Space-Based (SBR) constellation for the wide-area surveillance of ground and maritime targets for the Department of National Defence (DND). Ata result, it quantified the coverage performances of a limited number of SBR constellations, varying in number between one and four spacecraft, each equipped with a Surface Moving Target Indicator (SMTI) sensor. Constellation coverage performance in this case were evaluated based on revisit and response times obtained over selected areas of interest (AOI) and not performance as a function of detection, tracking, and identification of discrete surface moving targets. Satellite Tool Kit, a commercially available software suite that performs satellite performance analysis, was used to perform surveillance simulations and to produce the coverage results described in this report. The SMTI sensor parameters were obtained from specifications provided by Dr. C.E. Livingstone of DRDC Ottawa and from contract reports produced by EMS Technologies Canada, Ltd under the Space Based SMTI/SAR Systems Study. Three scenarios were used to evaluate the military potential of the simulated SBR constellations. The first considered a wide area surveillance mission over the Canadian territorial waters with a specific interest in the surveillance of northern Canada. The next two scenarios considered a limited Canadian SBR constellation being used to augment an allied SB
