Embodiment Construction

[0031] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0032] Such as Figure 4 As shown, the present invention is based on the dipole antenna active three-dimensional pulsed electric field strength measuring instrument, including probe 1, hollow metal connecting rod 2, detection circuit 3, power supply 4, detection circuit box 5, output interface 6, power switch 7. Probe 1 is composed of three small dipole antennas perpendicular to each other. The three small dipole antennas are perpendicular to each other to form a three-dimensional omnidirectional spherical electric field probe. The three dipole antennas are all metal cylinders with a length of 9mm. The diameter of the spherical probe is 3mm, and the shell of the spherical probe is made of glass fiber reinforced plastic, with a diameter of 40mm; the probe 1 is connected to the detection circuit box 5 through the hollow metal connecting rod 2,...
