At present,application of SystemVue is mainly concentrated on communication field.It is rarely used in the radar system simulation.SymtemVue has superior performance in simulation,which can satisfy the needs of simulation system in radar network.This paper is focused on its application in data fusion system of radar network.Firstly,the basic situation of SystemVue is introduced briefly.Then,aiming at fire control radar network and combined with Matlab,the data fusion system construction is completed based on SystemVue simulation platform,thus the feasibility of using SystemVue for simulating data fusion system is verified.And at the same time,the visibility and flexibility of SystemVue in system simulation is proved.For its unique advantages,SystemVue simulation software will have great application prospect in the field of radar system simulation.
