An extremely high frequency braking system and its scene adaptive waveform control method

Abstract

The invention provides an ultrahigh frequency braking system which comprises a waveform control unit, a millimeter wave beam radiating unit, an antenna reflector and a camera, wherein the millimeter wave beam radiating unit is connected with the waveform control unit, the camera and the antenna reflector are coaxial, the focal distance of the camera is variable, and the camera is used for obtaining the object distance d and feeding obtained distance information back to the waveform control unit. The waveform control unit comprises a storage unit used for storing control signals with different duty ratios and selects the corresponding control signal to control the millimeter wave beam radiating unit according to the object distance information fed back through the camera. The ultrahigh frequency braking system has the advantages that radiated millimeter wave beams of the braking system are Gaussian wave beams, a distance measurement device is introduced, so that a semi-closed-loop system is formed, and the waveform is adjusted adaptively. The ultrahigh frequency braking system is applied to an active stop rejection system, complexity of device operation can be effectively reduced, adaptive waveform adjustment of a device is achieved according to a scene and the distance of an object, the maximum effect of the system can effectively achieved, and energy is saved.

Description

technical field [0001] The invention relates to the fields of high-power microwave technology, tracking and aiming technology and automatic control technology, in particular to an extremely high-frequency braking system of an active denial system that can be used for multiple purposes such as dispersal, warning, anti-terrorism, and setting a specific isolation area. The control technology of the system adaptive waveform according to the scene. Background technique [0002] Such as figure 1 and figure 2 As shown, when the electromagnetic wave penetrates into the conductor, the depth attenuated gradually to e-1 times the surface amplitude due to energy loss is the penetration depth of the skin effect on the conductor. The deeper the wave enters the conductive medium from the surface, the smaller the amplitude of the field and the smaller the energy, which can be judged by comparing the size of the conductor with the wavelength of the electromagnetic wave in it. Millimeter ...
