Study on Hardware-in-the-loop Time-sharing Simulation Methods for Neted Radar

Hardware-in-the-loop(HITL) time-sharing simulation methods are proposed,which solve the problem of adopting one set of HITL radar to simulate neted radar.Two HITL time-sharing simulation methods are studied: one is named long-time-sharing netting method,whose sharing period is equal to the whole flight time of the target;the other is named short-time-sharing method,whose sharing period is equal to the radar sampling interval.First,an applied HITL system is introduced.Then the flows for the two methods are described, and the key process of the methods-data fusion algorithms are presented.Finally the advantages and disadvantages of the two methods are compared qualitatively in terms of four factors: configuration,tracking accuracy,application and anti-jamming.Some valuable conclusions are drawn.
