Abstract The key problem of calibration for low frequency ultra wide band synthetic aperture radar system is the acquisition of the scattering information of calibrators and suitable signal processing model. In this paper, the RCS of trihedral triangle reflector changing with the frequency and aspect angle is obtained using methed of moment and AWE method, and the calibration model is proposed based on time domain. The computer simulation is used to verify this calibration method, and result is agreed with the theory analysis.
