The invention discloses a radar simulation system based on an XML (Extensive Makeup Language) schema. According to the invention, the system framework, interface specification and operation statute of the radar simulation system are defined through the high abstraction of the radar simulation system architecture and full life-cycle development. The radar simulation system comprises a radar simulation setting module, a radar simulation engine interface module, a radar simulation tool set module, a radar simulation model library module, a universal simulation mode library module, a radar simulation link library module, a radar simulation configuration module, and the like. Through the invention, the reuse, integration, and interoperation of the radar simulation model are facilitated, and the gradual refining, evolution, analysis and evaluation of the radar equipment demonstration simulation can be effectively supported.
