1A new near field radar target and JEM modeling and implementation of radar target HWIL simulation system

摘要

This paper focus on modeling and the involved theoretical characteristics of the near field radar target and proposes a new modeling method based on multi-scattering centers. Multi-scattering centers modeling method is based on decomposition of components of the radar target.. The influence of JEM (jet engine modulation) is considered. JEM effect caused by the rotating-blades of aircraft engine can greatly disturb the useful signals scattered by target's body, therefore it must be considered in modeling and simulation of radar target like jet aircraft. HWIL simulation can be defined as a kind of real-time simulation system which uses hardware to replace the mathematical model of simulation. Radar target HWIL simulation system has become an important method on the research evaluating radar and replacing outfield test.
