A phased array radar digital simulation system and its simulation method

Abstract

The invention relates to a phased array radar digital simulation system, and belongs to the technical field of radar system simulation. According to the phased array radar digital simulation system, a system framework is divided into a main sub system and three auxiliary sub systems, wherein the main sub system is a radar workbench simulation sub system and the three auxiliary sub systems are a simulation scene control sub system, a radar main control computer sub system and a radar analysis and evaluation sub system. The functions of the radar workbench simulation sub system are perfected by adding a control word interpreting module, a coordinate conversion module, a flight path intersection model and a loopback word delivering module, and therefore the real-time closed loop simulation of the whole phased array radar system can be carried out. The phased array radar digital simulation system has the advantages of being good in generality, good in instantaneity and capable of achieving the closed loop simulation, and can be applied to the design of modern phased array radar systems.
