A new simulation model of fuse RF system

Based on the highlight method, this paper builds up the model of the radar target especially the near field. The database of the properties of near field, which is generated by the fuse antenna, is established using FDTD method. Combining simulation of circuit with computing of near field the simulator was made for fuse system. And by means of this simulator the imitative analysis and calculation on fuse system can be more reliable and accurate. In the end the result of time-domain simulation demonstrate that the simulator can be effectively applied in the synthetic test system to the fuse of the weapon system.
