基于L波段气象雷达的空中三维电场探测系统

以往采用的大气电场探测方法需搭建独立的电场探测系统，并且主要实现空中矢量电场的一个或两个分量的探测。该文介绍了一种新型空中电场探测系统，基于气象部门现有L波段气象雷达探测系统，采用新型3维电场传感器，构建了新型空中电场探测平台，实现了空中3维电场、温度、湿度、气压等气象信息的同步实时探测。系统中电场传感器采用了独特的结构设计和信号处理电路，在30 kV/m的电场测量范围内，分辨力可达20 V/m，线性度优于1%，可以连续探测地面至15000 m高空的3维电场强度，为飞行器升空提供安全保障。

Spatial Three Dimensional Electric Field Measuring System Basing on L-Band Meteorological Radar

The independent spatial electric field detecting system should be put up in previous measurement.And the system measures mainly one or two directions of the spatial electric field.This paper presents a novel three dimensional spatial electric field measuring system.In the system,three-dimensional electric field sensor is adopted to detect the spatial electric field.Basing on the existing system of the L-band meteorological radar in meteorology department,the platform of measuring the spatial electric field is constructed,which can detect the meteorological information such as temperature,humidity and pressure synchronously.The unique mechanical structure and the novel signal processing unit are implemented in the sensor system.The detector resolution reaches 20 V/m,and the linearity is better than 1% within the range of-30 kV/m to +30 kV/m.The system can detect the three dimensional electric field at the height of 0~15 km,which provides safety guarantee for the aerocraft.
