Precise frequency division algorithm for residual aperture‐variant motion compensation in synthetic aperture radar.

The effects of complicated motion error on synthetic aperture radar have been analysed. A precise frequency‐division is proposed based on the precise angle‐frequency relation. The proposed method completely compensates the residual aperture‐variant motion and can be integrated into the traditional image formation algorithms directly. Both the simulated data and real airborne data have been applied to validate this method. [ABSTRACT FROM AUTHOR]
