Abstract :
A generalized formulation of azimuth spectrum for high precision processing on complicated trajectory of both ECSA and EFSA is derived. Based on the method of series reversion (MSR), the azimuth spectrum on complicated trajectory incorporates a new curvature factor for an identical formulation comparing to the one of ideal trajectory. A pretreatment of Range Walk Correction (RWC) is proposed to decrease the complication of imaging. Finally a monostatic SAR configuration is covered to illustrate the validity of the proposed algorithm.
