A Novel Design of SAR Scattering Signal Simulator Based on AWG

摘要：

Synthetic Aperture Radar (SAR) raw signal simulation is crucial for SAR system design and processing algorithms. This paper proposes the simulation method of SAR RF signal via utilizing Arbitrary Waveform Generation (AWG). At first, the SAR imaging principle is analyzed. Then, the space-borne SAR scenario model is constructed. The echoes of point target are calculated, which is impulse response of the SAR signal acquisition. At the end, based on the scattering model expressions of a random roughness surface and the electromagnetic wave shadow theory, the Radar Cross Section (RCS) simulation parameters of terrain target is calculated. 2D-FFT method is utilized to improve simulation efficiency significantly.
