Abstract
Synthetic Aperture Radar (SAR) is one of the key components in missile guidance and control system for its functional capability of target identification and scene matching. It is very important to test the SAR system infield by using Radio Frequency Simulation System (RFSS). Since traditional method failed to simulate amplitude and phase modulation caused by antenna pattern and radome exactly, this paper proposes a new concept of using multi-element arrays to radiate electromagnetic wave simultaneously, which can simulate the spatial amplitude and phase features of radar target scattering signal. The simulation results demonstrate that the target signal generated with the proposed method has obvious characteristics of peak shift and sidelobe rise after imaging. And the radar images are more blurred and mottled compared to the old method, at the same time, are more realistic and credible. So that it could be a reference to the practical application of Hardware In the Loop (HWIL) simulation.
