Embodiment Construction

[0023] The embodiments of the present invention are designed according to the principles of the present invention, and the present invention will be further described below in conjunction with the accompanying drawings and the following specific embodiments.

[0024] like figure 1 Shown is the diagram of the tolerance curve of the human body to electromagnetic waves, where the abscissa represents the time (Time) in seconds, and the ordinate represents the temperature of the skin (SkinTemperature) in degrees Celsius. Different curves extending from the origin of the coordinates correspond to According to different power density / intensity (BeamIntensity), the two dotted lines parallel to the abscissa are the pain threshold of the human body (above the threshold will feel pain) and the maximum pain tolerance value, and the dermalnecrosis curve is the corresponding skin Necrosis (Fluence) energy density threshold (12J / cm 2 )curve. It can be estimated from the above relationship ...

Abstract

The invention relates to a denial system comprising an electromagnetic wave transmitting unit, a control unit and a signal generation unit. The control unit has multiple scanning modes, such as a fixed-point mode, where sensor positioning according a target or manual positioning is performed and the electromagnetic wave transmitting unit is controlled to track the target, and a longitudinal scanning mode, where the horizontal direction of the electromagnetic wave transmitting unit is kept unchanged and areas of different distances are periodically scanned by changing a pitching angle. The denial system has the advantages that a denial system scanning mechanism automatically scans from left to right or from right to left in the transverse direction, denial beams act on targets in a wide area; in the area scanning mode, the denial system scanning mechanism regularly scans in the azimuth and pitching direction, the system is applicable to setting restricted zones or dispelling targets and is suitable for concentrated target areas; in the search mode, the system is applicable to searching targets in a certain area.

Description

technical field [0001] The present invention relates to a denial system that can be used for multiple purposes such as dispersal, warning, anti-terrorism and setting a specific isolation area, and specifically designs multiple scanning modes of the above denial system. Background technique [0002] 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 waves (30-300GHz) rarely exist in nature, but animals (including humans) will feel uncomfortable with them in a short period of time. Due to the small skin depth of millimeter wave, foreign countries are studying its biol...
