Embodiment Construction

[0022] The present invention is further described in detail with reference to the examples.

[0023] First, before the test, the electroacoustic alarm controller is placed in the test area. The electroacoustic alarm controller in this embodiment adopts the JDSK-EW type electroacoustic alarm controller. The signal receiving antenna is placed in an outdoor open space, and the two are connected by a special cable; after the connection is completed, turn on the power switch of the device, set it to the remote alarm state, and receive the remote control command issued by the central station; when the signal is received, the corresponding indication The light is on, and the test personnel can judge the damage of the electroacoustic alarm controller by observing the change of the working state of the controller;

[0024] The damage effect test of the multi-band narrowband high-power microwave to the electroacoustic alarm controller is carried out according to the following steps:

Abstract

The invention discloses a multiple wave band narrowband high power microwave-based damage effect test method for an electroacoustic alarm controller. The electroacoustic alarm controller is placed in a test zone, and the method comprises the following steps: in step a1, L wave band high power microwave radiation is set in a system, and the electroacoustic alarm controller faces right to radiation wave waves; in step a2, the electroacoustic alarm controller faces sideways to the radiation wave waves; in step a3, the electroacoustic alarm controller faces in a direction opposite to the radiation waves; in step a4, a polarization mode is changed to a vertical polarization mode; in step a5, a wire cable is hidden in wave absorbing material; in step a6, minimum pulse energy density in steps from step a1 to step a5 is chosen as an interference threshold value for a sample; in step a7, the sample is changed, the steps from step a1 to step a6 are repeated; in step a8, a threshold value range of damage caused on the electroacoustic alarm controller by a wave band high power microwave; in step a9, the microwave radiation system is orderly adjusted to be an S wave band microwave radiation system, a C wave band microwave radiation system and an X wave band microwave radiation system; the test steps from step a1 to step a8 are repeated. The damage effect test method is advantaged by well-organized structure, strong pertinency, easy-to-implement property and the like.

Description

technical field [0001] The invention belongs to the field of research on electromagnetic damage effects, and mainly relates to a method for performing damage effect tests on electroacoustic alarm controllers by using multi-band narrow-band high-power microwaves. Background technique [0002] The civil air defense warning issuance control system is an important part of the civil air defense system, and plays a vital role in urban air defense and personnel evacuation. As the core equipment of the system, whether the electroacoustic alarm controller can work normally in the face of the threat of electromagnetic pulse weapons is a problem that must be concerned, which requires experimental research on its electromagnetic damage effect. [0003] High-power microwave generally refers to microwaves with a power above 100MW and a frequency in the 300MHz-300GHz band. This weapon can be fixed on the ground, or it can be mounted on a vehicle, ship, airborne or missile. It can radiate ...
