Three-Dimensional Pulse Electric Field Test System with Optical Fiber

Abstract

A three-dimensional pulse electric field system with optical fiber is developed. It is made up of electric field testing probe, optical transmission system, optical receiver and display, which can realize three-dimensional pulse electric field measurement in the whole space. This paper introduced the three-Dreceiving antenna, the three-D electric field signal synthesis and photoelectric receiver and then analyzed the design of the three-D receiving antenna and the method of three dimensional electric field synthesis. At last, the performance of the testing system is measured. Results show that the system has good test performance whose bandwidth can reach 1KHz-1GHz, dynamic range can be up to 60dB.
