Abstract
Algorithms have been derived for evaluating the signal to interference ration (SIR) for a Displaced Phase Centre Antenna System in a space-based configuration on a burst by burst basis. This work results as an extension of previous work conducted by CRC and Atlantis Scientific. A simulation package, DPCASIM3, was created to evaluate the resulting equations numerically. Results show that, provided statistical independence between clutter patches, the nature of the probability distribution of the reflectivity has no observable effect on the SIR curves. However, the mean value of the clutter RCS remains an important parameter. Also presented is an algorithm and code for generating discrete scatterers uniformly over the radar footprint. Under optimal filtering conditions; discrete scatterers act only to cause an overall degradation of the SIR.
