Abstract
Moving target parameter estimation algorithms have been developed previously for airborne (or flat Earth) geometry. Subtle differences exist in migrating from a flat stationary Earth geometry to a spherical rotating Earth geometry. Factors, such as orbital parameters and spacecraft centripetal acceleration, must be taken into account. In addition, the dynamic antenna squint implemented in the RADARSAT-2 satellite for Earth motion compensation needs to be modelled into the algorithms. This technical memorandum derives the spaceborne version of the algorithm, based on the fractional Fourier transform and along-track interferometry, previously developed for the Convair 580 radar.
