In order to solve the problem that the traditional pulse sensor can only measure the literal direction of electric field

we designed a 3-D omnidirectional electric field sensor.The sensor is made up of 3 electrically small antenna which is mutually orthogonal

cooperates with the optical fiber transmission system

and can realize the measurement of the whole space pulse electric field.The optimum design parameters of the 3-D pulse electric field sensor probe are determined according to the simulation of the electric field sensor on electric field under test and the influence of load impedance and the effect of antenna size characteristics of the test.Thereby

a 3-D pulse electric field sensor probe is made and its mean performance indexes are tested.The results show that it has a good broadband performance.The test bandwidth can reach 1 kHz

1

GHz and its dynamic range is more than 60 d B

meeting the design requ

irements.
