A novel accessional phase compensation method for InISAR imaging under squint mode

Accessional phase component needs to be estimated and compensated when interferometric inverse synthetic aperture radar (InISAR) imaging under squint mode. Base on strict analysis and deduction, we proposed a novel method for the compensation of accessional interferometric phases under squint mode. Comparing to precedent methods, new method is more convenient to implement with equivalent precision. Simulation results demonstrate the effectiveness of our method.
