Embodiment Construction

[0024] 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.

[0025] Such as 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 skin temperature (Skin Temperature) in degrees Celsius, different curves extending from the origin of the coordinates Corresponding to the situation of different power density / intensity (Beam Intensity), the two dotted lines parallel to the abscissa are the pain threshold of the human body (pain is felt above this threshold) and the maximum pain tolerance value, and the dermal necrosis curve is Corresponding energy density threshold of skin necrosis (Fluence) (12J / cm 2 )curve. It can be estimated from the above relations...

Abstract

The invention discloses an active denial system. The active denial system comprises an electromagnetic wave transmitting unit, a control unit and a signal generating unit, wherein various power control signals are stored in the signal generating unit, and the signal generating unit is used for controlling the duty ratio of electromagnetic waves transmitted by the electromagnetic wave transmitting unit. The active denial system has the advantages that a denial system scanning mechanism conducts automatic scanning in the transverse direction from left to right or from right to left, and a denial wave beam acts on an objective in a wide area; in an area scanning mode, the denial system scanning mechanism conducts scanning in the azimuth direction and pitching direction according to a rule so that a forbidden zone can be set or the objective can be dispersed, and the active denial system is suitable for an objective-intensive area. A searching mode can act on a certain area for objective searching. The setting of the modes has great significance for designing the system, improving the overall efficiency and reducing system redundancy, a control program can be generated automatically, and mode conversion can be generated automatically.

Description

technical field [0001] The present invention relates to an active denial system that can be used for multiple purposes such as dispersal, warning, anti-terrorism and setting a specific isolation area, and specifically designs the power adjustment range of the above active denial system under different working modes so that the system Maximize efficiency. Background technique [0002] When the electromagnetic wave penetrates into the conductor, it gradually attenuates to the e of the surface amplitude due to energy loss -1 The depth of times 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 p...
