Detailed description of the invention
For ease of understanding, it is embodied as structure and workflow is described below here in connection with accompanying drawing 2-9 to of the present utility model:
Row feedback direct linkage type secondary radar antenna structure of the present utility model, main body is made up of 1 shell body, 35 row feedbacks, 2 side feeding network box bodys and 1 middle part feeding network box body.Certainly, the actual man-hour side feeding network box body of adding is alternatively the even-evens such as 4. After above-mentioned parts overall package, propped up row feedback 10 and corresponding feeding network box body by antenna holder a holder, support purpose to play to fix.
The assembled relation of above-mentioned parts is: as shown in figures 2-6, and 35 row feedthroughs are crossed fixed frame 20 and postponed according to a determining deviation parallel side-by-side shape cloth, then are fastened on shell body 60 front place. Side feeding network box body 32 and middle part feeding network box body 31 are installed on the interior plate face in shell body 60 front by securing member, and are stretched out from the perforate in shell body 60 front by the male form radio frequency (RF) coaxial connector 52 of the waterproof on each feeding network box body as Figure 7-9. Realize being electrically connected to each other by coaxial cable 40 between the abutting end of side feeding network box body 32 and middle part feeding network box body 31. Female radio frequency (RF) coaxial connector 51 in row feedback 10 is directly connected to the male form radio frequency (RF) coaxial connector 52 on side feeding network box body 32 and middle part feeding network box body 31. So far, above-mentioned all parts have collectively constituted the specific antenna front with certain function, its effect is that by required spatial distribution, radar signal is transmitted into space, and receives the radar signal reflected from extraterrestrial target, suppresses to come from the unwanted interference signal in space simultaneously.
Shown in as in Figure 3-5, shell body 60 is rectangular box, overall dimensions: 8044mm × 420mm × 300mm. Shell body 60 entirety, by adopting agitating friction to be welded between 4mm thickness bending aluminium sheet and aluminium section bar, is welded in position, shell body front as the fixing aluminium section bar that matches with feeding network box body. After shell body 60 welding, need the installed surface of the above-mentioned aluminium section bar of this shell body 60 of polish, to ensure the Geometrical Tolerance Principle such as the flatness of installed surface, Kong Wei, to facilitate subsequent installation row feedback 10. Centre position, shell body 60 front machined the small sircle hole of 35 diameter 15mm according to a determining deviation, for being stretched out from shell body 60 front by the male form radio frequency (RF) coaxial connector 52 on side feeding network box body 32 and middle part feeding network box body 31. Shell body 60 both sides and have 10 rectangular apertures 61 below altogether, for installing, the corresponding feeding network box body that overhauls in shell body 60 and coaxial cable 40, are respectively mounted sealing port lid 62 outside rectangular apertures 61.
Row in Fig. 7-8 are presented 10 overall dimensions and are taken 1680mm × 266mm × 40mm, install 1 female radio frequency (RF) coaxial connector in its centre position, back side, and this radio frequency (RF) coaxial connector is connected with the micro-strip dipole antenna within row feedback 10. Side feeding network box body 32 overall dimensions: 2457mm × 330mm × 16mm, before it, 11 male form radio frequency (RF) coaxial connectors are equidistantly installed in centre position. Middle part feeding network box body 31 overall dimensions: 2857mm × 330mm × 16mm, 13 male form radio frequency (RF) coaxial connectors are equidistantly installed in centre position before it. Article 35, the female radio frequency (RF) coaxial connector 51 in row feedback is directly connected to the male form radio frequency (RF) coaxial connector 52 on side feeding network box body 32 and middle part feeding network box body 31. This utility model manufacturing cost is lower, and shell body overall dimensions is less, and antenna weights also can be reduced further. Can be seen that from Fig. 2-5, connection between row feedback 10 and each feeding network box body greatly simplify the original coaxial cable gathered, attachment structure is more succinct, direct-connected mode obviously also reduces the signal of telecommunication loss between row feedback and feeding network box body accordingly, it is adaptable to the low modern work demand installing and using cost, high workload efficiency and volume miniaturization of user at present.
