Description
Technical field
The utility model relates to direction-finding station technical field, particularly relates to a kind of direction finder antenna.
Background technology
Direction-finder antenna is the important component part of radio direction finding equipment, the structures shape of the direction-finder antenna performance index of radio direction finding equipment, as operating frequency, sensitivity, anti-interference, direction finding timeliness etc.
Direction-finder antenna product relevant both at home and abroad at present adopts fixed design mostly, and these designs are irremovable and very inconvenient, there is direction finding blind area, and sensitivity are low, antijamming capability is more weak, direction finding timeliness is low.And other direction-finder antenna products mainly adopt single directional antenna constantly to rotate, but due to single directional antenna rotate a circle need cycle long, therefore its direction finding efficiency is low, poor to the Signal catching capability of movement.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of direction finder antenna, can simultaneously carry out following the tracks of and scanning completes direction finding in all directions.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of direction finder antenna, described direction finder antenna comprises base plate and radome, described radome to be fixed on described base plate and to form closed cavity with described base plate, switch matrix is provided with in described closed cavity, column and polylith mounting panel, described switch matrix is arranged on described base plate, described switch matrix is integrated with multiple switch, described column to be fixed on described base plate and vertical with described base plate, described polylith mounting panel centered by described column circumferentially vertical distribution on described base plate, be fixed with in the upper end of described column multiple with described column for the equally distributed front end antenna element in the center of circle, the quantity of described front end antenna element, the quantity of described mounting panel and the quantity of described switch all equal, described in each, the outer surface of mounting panel is provided with support arm connected vertically with described mounting panel, the end both sides of described support arm are separately installed with low-frequency vibrator, two low-frequency vibrator on support arm described in each form a low frequency end antenna element, described multiple front end antenna element and described multiple low frequency end antenna element match one by one, described switch is used for the front end antenna element that matches described in gating and low frequency end antenna element.
Preferably, the quantity of described mounting panel is 5.
Preferably, described multiple front end antenna element and described support arm stagger mutually, and are projected in the centre of two described support arms.
Preferably, described radome is fixed by screws on described base plate.
Preferably, the material of described front end antenna element and described low-frequency vibrator is aluminium alloy.
The beneficial effects of the utility model are: the situation being different from prior art, direction finder antenna of the present utility model switches front end antenna element and the low frequency end antenna element of multiple circle distribution by switch matrix, thus realizes carrying out following the tracks of and scanning completes direction finding in all directions.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model direction finder antenna embodiment.
Fig. 2 is the front end antenna element of the utility model direction finder antenna and the schematic top plan view of low frequency end antenna element.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Please also refer to Fig. 1 and Fig. 2.The direction finder antenna of the utility model embodiment comprises base plate 1 and radome 2, radome 2 to be fixed on base plate 1 and to form closed cavity 3 with base plate 1, switch matrix 4 is provided with in closed cavity 3, column 5 and polylith mounting panel 6, switch matrix 4 is arranged on base plate 1, switch matrix 4 is integrated with multiple switch 41, column 5 to be fixed on base plate 1 and vertical with base plate 1, polylith mounting panel 6 centered by column 5 circumferentially vertical distribution on base plate 1, being fixed with multiple is the equally distributed front end antenna element 51 in the center of circle in the upper end of column 5 with column 5, the quantity of front end antenna element 51, the quantity of mounting panel 6 and the quantity of switch 41 all equal, the support arm 61 connected vertically with mounting panel 6 is provided with at the outer surface of each mounting panel 6, the end both sides of support arm 61 are separately installed with low-frequency vibrator 62, two low-frequency vibrator 62 on each support arm 61 form a low frequency end antenna element, multiple front end antenna element 51 matches one by one with multiple low frequency end antenna element, the front end antenna element 51 that switch 41 matches for gating and low frequency end antenna element.In the present embodiment, the quantity of mounting panel is 5, then the quantity of front end antenna element 51 is all equal with the quantity of switch 41.Alternatively, the material of front end antenna element 51 and low-frequency vibrator 62 is aluminium alloy.
Wherein, multiple front end antenna element 51 staggers mutually with support arm 6, and is projected in the centre of two support arms 6.Radome 2 is fixed by screws on base plate 1.
Front end antenna element 4 in the direction finder antenna of the utility model embodiment is logarithm periodic antenna.Can gating antenna element 4 by switch matrix 4.Specifically in use, by the switch 41 on diverter switch matrix 4, get final product front end antenna element 51 and the low frequency end antenna element of gating a pair pairing, switched fast by the front end antenna element 51 of all directions and low frequency end antenna element, can follow the tracks of fast and sweep signal, thus signal acquisition completes direction finding, direction finding efficiency can be improved.
