Description
Technical field
The present invention relates to millimeter wave antenna technical field, specifically refer to a kind of millimeter wave dual reflector antenna with near-field uniform wave beam.
Background technology
Active denial system (ADS based on high-power millimeter wave, Active Denial System) be that the novel non-fatal crowd of one that the U.S. proposed in early 1990s disperses equipment, its basic principle is the high-power millimeter wave beam by be about 3mm to target group's radiated wave, within the several seconds, make human body skin produce insufferable scorching hot pain and flee from by the light of nature this region, reach the object of preventing and dispersing a crowd.
The high-power millimeter wave antenna of abroad having developed at present all adopts focused radiation mode, make the EFFECTIVE RANGE wider range in near-field region, but the power density of the wave beam that this mode produces in the zone of action changes very violent, existence is higher than the even higher position of effective power density twice, if target group is positioned at the too high position of these power densities and can not flees from time, will probably cause third-degree burn; If crowd is positioned at the too low position of power density, the effective utilization of ADS system will reduce greatly, cannot play the effective defence effect to target.Therefore be badly in need of a kind of high-power millimeter wave transmitting antenna near field with even wave beam, in the distance range of expecting, produce power density and the basically identical millimeter wave wave beam of wave beam radius, so both can expand the effective range of high-power millimeter-wave radiation system, can guarantee again the personal safety of target.
Summary of the invention
The object of the invention is to invent a kind of millimeter wave antenna that can produce even lip pencil wave beam within the scope of the certain distance of antenna near-field, by the curved surface of major and minor reflecting surface is carried out to Shape design, produce special Antenna aperture amplitude and PHASE DISTRIBUTION, thereby within the scope of the certain distance in near-field region, obtain the uniform lip pencil wave beam of beam power density and wave beam radius, solve when at present Active denial system adopts focusing millimeter wave antenna in the world near field wave beam with the violent deficiency of variable in distance.
The technical solution used in the present invention is: a kind of millimeter wave dual reflector antenna with near-field uniform wave beam, comprise pedestal, primary reflection surface, subreflector and corrugation loudspeaker feed source, described corrugation loudspeaker feed source is fixed on pedestal, at the front of corrugation loudspeaker feed source fixed joint reflecting surface, at the fixing primary reflection surface in the rear of corrugation loudspeaker feed source; The central area of described primary reflection surface is the ellipsoid type of approximate focus, and primary reflection surface is the ripple underlying surface type of ring-type convex-concave composition near outer edge region.
In technique scheme, described corrugation loudspeaker feed source reflects to form actinal surface electric field for twice through subreflector, primary reflection surface, and the amplitude of described actinal surface electric field is symmetrical parabola shaped distribution, and edge illumination is 0.
In technique scheme, the phase center region of described actinal surface electric field is for falling parabola shaped distribution, and edge is symmetrical hunting.
In sum, owing to having adopted technique scheme, the invention has the beneficial effects as follows: by improving the primary reflection surface of dual reflector antenna, the millimeter wave wave beam giving off from Feed Horn is after subreflector and primary reflection surface two secondary reflections, form described special actinal surface PHASE DISTRIBUTION, all very uniform lip pencil wave beams of power density and wave beam radius in the distance range of near field 1.2m ~ 4.0m, have been produced, shake is less than 10%, can be widely used in the fields such as millimeter wave short-haul connections, mm-wave imaging and millimeter wave power wireless transmission.
