Abstract

The performance trade-offs required for a small satellite Synthetic Aperture Radar (SAR) system designed to measure surface deformations using persistent scatterer interferometry (PSI) are investigated. Existing X-band satellite data is systematically deteriorated to account for the increased range resolution and Noise-Equivalent Sigma Zero (NESZ). It is found that with a NESZ below 0 dB the deformation signal of a selected region-of-interest (ROI) can be captured with mean absolute errors of 5mm and 15mm, for ground range resolutions of 5m and 20m respectively. This analysis is used to develop preliminary SAR system designs suitable for small satellites.
