用于生命探测的微功率冲击雷达天线设计

A power antenna designed to shock radar

用于生命探测的微功率冲击雷达(MIR)技术实现的关键之一是天线设计。本文针对系统对天线的要求,分析设计了一种轴向螺旋天线,并通过三维立体仿真软件HFSS10进行仿真,得到比较理想的增益波瓣图和反射系数图。结果表明所设计的螺旋天线能够满足系统的技术要求。

The key technology of micropower impulse radar used life-detection lies on how to design antenna.This paper analyses demand to antenna for system.The axial helix antenna is designed and simulated by three-dimensional simulation software——HFSS10 with satisfied results of the gain pattern and the.The final result indicate the helix antenna may achieve system requirements.
