Abstract

It is an important significance for SAR radiometric calibration accuracy to select a proper code sequence about active coded transponder (ACT), in the process of active coding radiometric calibration using synthetic aperture radar (SAR). According to the principle of active coding radiometric calibration, a signal processing model of active coded reflected signals is proposed in this paper. And m sequences, Gold sequences and random sequences are studied. Simulation experiments with the compression of SAR azimuth signals are carried out.
