2D System Simulation Modeling for Millimeter Wave Interferometric Synthetic Aperture Radiometer

The purpose of this paper is to develop an accurate imaging model to simulate the imaging process of millimeter-wave Interferometric Synthetic Aperture Radiometer(InSAR), enabling system designers to accurately predict the imaging effect and deeply analyze the impact of various parameters on InSAR performance. The core advantage of this model lies in its ability to accurately characterize the target radiated signals and the receiver received signals in the time domain, which significantly enhances the accuracy of the model. The effectiveness of the imaging model has been validated by 2D simulation experiments, providing designers with a powerful tool to guide the construction and optimization of real systems, thereby improving the overall performance of millimeter-wave InSAR systems.
