Abstract
The coverage for air surveillance available with constellation of space-based radar satellites was simulated. The coverage was modelled as an annulus, defined by the grazing-angle limits of 3 degrees and 50 degrees, moving over the earth. The number, altitude, and orbital inclination of the satellites were varied, and targets were placed at various latitudes. A constellation of seven satellites, at 1000 km altitude, and 80 degrees inclination gave nearly continuous coverage at the pole. Equivalent coverage was obtained with fewer satellites at higher altitudes, and lower orbital inclination.
