Abstract :
The integrated sidelobe ratio (ISLR) arising from errors in motion compensation is one figure-of-merit in evaluating the fidelity of modern SAR imagery. An analytical closed-form expression is derived here as a function of SAR array time, underlying motion-sensor accuracy, and limiting data bandwidth.
