Description
Technical field
The present invention relates to a kind of installation accuracy detection method of planar array antenna face.
Background technology
It is the feeder system of main body that antenna reaches with the antenna, thereby is to realize radar emission and the important component part that receives space electromagnetic wave realization radar basic function.Radar antenna has curved face type and two kinds of diverse versions of array type substantially, because array antenna helps realizing the high maneuverability and the Low Sidelobe of radar more, thereby has obtained increasingly extensive application, has become the primary structure form of modern radar.
For the traditional reflective surface antenna; The profile great majority of array antenna are the plane; Profile is more regular; It is by some mutual orthogonals of beam and add the connection structure that upper enclosure frame constitutes front skeleton and the some of trave formula the multi-in-line source is installed on the front skeleton in length and breadth, thereby has formed complete front, outer likeness in form upright or " door-plate " stretching across.As the product of electromechanical integration, the version of array antenna, size, precision etc. all receive the restriction of electric property, and directly influence the complete machine telecommunication index of radar, and wherein the precision of antenna reflective face is just directly related with the working frequency range of radar.Because the surface error of each point is different on the front, the antenna actinal surface no longer is a cophasal surface, thereby antenna pattern is changed, and gain descends, and minor level raises.Theoretical analysis shows that what really determine electrical property is the size and the distribution situation of front error, i.e. the maximal value of mean square of error root, rather than individual point error.
The function of radar principle has determined must occupy a commanding position under antenna in working order; Its high maneuverability also requires between work and travel position, will change mutually easily and efficiently, so the front of planar array antenna is divided into upper and lower two usually and is convenient to folding the stretching, extension and realizes above requirement.Because planar array antenna is rectangular, physical dimension is bigger usually: length >=5m, wide >=3m.In working order down; Front main shaft and incomplete level; The certain angle (8 °～15 °) of generally all will swinging back, therefore, how whole front is installed and the surface accuracy that reaches antenna requires in other words; How the surface accuracy of planar array antenna assembles quickly and accurately, adjusts, detects---and particularly how surface accuracy detects under the duty of tiltedly holding up, and just becomes difficulty, emphasis in the radar manufacturing.
The process and the method for existing detection antenna array surface accuracy comprise following step: after 1) upper and lower skeleton processing coated is accomplished; Physical dimension by the antenna array skeleton is arranged, cleans the assembly yard, is taken corresponding assembling plate; On flat board, take and adorn large-scale right angle backer; And with frame level and transit, the level(l)ing washer level is also vertical with backer's face; 2) crane cooperates, and will go up the lower back frame and link with directly having backing with bolt, pressing plate, and the crane cooperation is loaded onto journal stirrup plane or flange face and last lower back frame with bone and linked, the general assembly of formation skeleton; 3) the antenna pedestal assembly with radar is lifted on the assembling plate; Be level with frame level school antenna pedestal assembly installed surface and also link with pressing plate, bolt and assembling plate, crane cooperates, and the general assembly of lifting skeleton connects the vertical frame assembly that is assembled into the antenna pedestal assembly; 4) take front and the side of tripod at frame assembly, and set up collimating telescope, transit, an adjustment skeleton in school is parallel repeatedly reaches perpendicular to horizontal line; 5) transit cooperates the indium steel ruler, and the waveguide mounting blocks plane on the skeleton is detected, adjusted, and guarantees flatness error≤0.2mm; 6) prepackage waveguide mount; Wouldn't be fastening; With collimating telescope (containing tripod); Vertically detect, adjust the linearity of each serrate slot one side of waveguide mount line by line; After guaranteeing straightness error≤0.2mm, cooperate spirit-leveling instrument, pit gauge, guarantee flatness error≤0.2mm each the baseplane adjustment of waveguide mount serrate slot, repair level; And according to data measured value (l) and count (n) that measure; Calculate the arithmetic mean
and the residual error (V) of measurement data, calculate front trueness error σ:
according to the Bezier formula adorn fixedly waveguide mount, fastening waveguide mount screw then; And the hole installing and locating pin that drills and reams, line source is installed at last.The antenna movement test comprises rotates test, roll-over test and pitching test.
The maximum shortcoming of this kind detection method is: repeat surface accuracy after can't detecting antenna array rotation, upset, luffing; In the time of can't detecting, eliminate radar duty (8 °～15 ° angles of swinging back), the skeleton deadweight causes framework deformation, causes the influence to the antenna array surface accuracy; Can't detect the elevation angle error of antenna, and the vertical assembling waveguide mount of skeleton, vertically, when laterally adjusting bottom land flatness, side linearity one by one, line by line, big, the inefficiency of workload; And need purchase collimating telescope; And in testing process, for overproof part, because vertical assembling; Therefore it is also very difficult to carry out local repair, adjustment, and personnel are also dangerous because of being in high-rise working for a long time.
