The computer simulation results illustrate that the squint range model has less error and CA-ECS algorithm can be used to accomplish motion compensation with acceleration efficiently.

RD algorithm based on minimum entropy criteria carries out the correction phase errors caused by high squint Angle via searching error coefficients for improving the imaging focus effect.

The simulation results prove that roll error and its stabilization and spaceborne SAR squint angle are the key factors to SAR resolution performance errors. The conclusion is valuable t…
