Wavenumber-domain imaging algorithm for high squint SAR based on azimuth variation range model
Due to the acceleration in the moving of the platform, the SAR imaging of highly squinted
maneuvering platform becomes a problem to be solved urgently. The majority of currently
existing range models fail in taking the azimuth-variation into consideration, so the well-
focused images are not obtained. To solve these problems, a new azimuth-variation range
model under the non-linear trajectory caused by acceleration is constructed. Based on this
model, a wavenumber-domain imaging algorithm for high squint SAR is proposed, which …
