Review of Radar Imaging Simulation

Radar imaging for military flight simulator training plays an important role in simulation training because of its advantages of no limitation of time and space, controllability and strong security. In this paper, three main ground surrveying and mapping methods (RBM, DBS and SAR) for airborne fire control radar, domestic and foreign fighter radar models and their imaging systems are introduced. The research and development status of foreign radar imaging simulation software and domestic radar simulator are described. The advantages and disadvantages of existing products, their applicable scope and technologies are described in detail. The main methods and realization process of radar image simulation are summarized, which are divided into three categories: echo signal simulation, transfer function and fusion of radar image features. It is predicted that radar imaging simulation will develop in the direction of establishing general database, expanding imaging range, and improving real-time performance and fidelity.
