Effect of the ionosphere on defocusing of space-based radars
Space-based synthetic aperture radars are detrimentally affected by electron density variations in the ionosphere, which cause signal phase variations resulting in image defocusing. Published in the leading journal in this field a novel method is developed to estimate such variations from analysis of high cadence ionospheric measurements. The probability of image degradation is quantified with implications for radar orbit, design and operation. Recognising that similar high cadence data is limited, an analytic approach to calculating this degradation is developed; this approach has wide engineering applicability. This work includes a collaborative author from the Australian Bureau of Meteorology.
