A simulation study of the omega-k SAR algorithm for the highly squinted case with application to runway imaging

Nail Cadalli and David C. Munson

The wavenumber-domain SAR algorithm is studied for the case of a high squint angle with particular application to runway imaging from an approaching aircraft. The feasibility of using the algorithm for this application is shown by point target simulations which indicate that aberrations due to the high squint angle can be eliminated with finer interpolation in the processing.
