Description
Technical field
The present invention relates to radio frequency simulation field, specifically a kind of RF array array antenna calibrating installation. Main Function is that from position, angle, distance, auxiliary improves a kind of device of array antenna mechanical location calibration accuracy in conjunction with laser measurement.
Background technology
Radio frequency Guidance and control Semi-Physical Simulation Test System develops the important emulation platform in proof procedure as air defence missile, its confidence level height is the link being concerned about for people, this emulation platform have to provide simulated environment reliable, believable for the development of guided missile with checking such that it is able to realizes carrying out the realistic simulation of air defence missile whole firing process in test chamber. Radio frequency array antenna system is then very important ingredient in this set emulation platform, its function be simulated missile in outfield by the complex electromagnetic environment faced by reality, it may be said that the realistic simulation precision of this system will have influence on the confidence level of whole emulation platform, if not being provided that desirable simulation precision, the HWIL simulation of air defence missile will not known where to begin yet.
Therefore, in the process of construction of radio frequency Guidance and control Semi-Physical Simulation Test System, having a very important step is exactly that radio frequency array antenna system carries out being accurately positioned and calibrating of mechanical location. This calibration process is typically with a set of RF calibration device and carrys out the radio-frequency radiation signal of receiving array antenna, and by carrying out the measurement on position than equivalent way. But find in actual application, if the method only with radiofrequency signal measurement yet suffers from some shortcomings part, being subject to the impact of the actual test environment in darkroom in the process of test, wavelength is longer easily produces the problem that Range Profile is fuzzy in range finding. Further, in the face of calibrate bigger darkroom, and a greater number electromagnetic horn composition radio frequency array time, due to cannot be quick, determine wavelength distance accurately, to radio frequency aerial mechanical location can increase again huge workload.
Summary of the invention
For solving easily to produce in range finding the problem that Range Profile is fuzzy, it is desirable to provide one can improve range finding speed, accurately determine a kind of RF array array antenna calibrating installation of wavelength distance.
A kind of RF array array antenna calibrating installation provided by the invention, including radio-frequency radiation signal receiver, described radio-frequency radiation signal receiver includes reception antenna, described antenna calibration equipment also includes the standard antenna perpendicular with being calibrated active antenna polarization mode, described radio-frequency radiation signal receiver is installed laser ranging component, described laser ranging component includes laser emitting source, thin film and laser and the film coating of transmission radiofrequency signal can be reflected, it is surrounded by described thin film at the actinal surface place of the RF array array antenna being calibrated, described film coating is covered in the RF array array antenna central area being calibrated.
The work of RF array array antenna alliance calibration is based on the principle of the relevant interferometer of width. For ensureing that target antenna directional diagram axis can accurately point to the centre of gyration (i.e. the centre of sphere of front) of turntable, it is possible to adopt and be calibrated than width mode; For completing the calibration to each passage radiation signal phase equalization of aerial array, it is achieved the apparent Angle Position of synthesis target is calibrated, it is possible to adopt ratio phase mode.
The polarisation angles measurement of radio frequency array antenna system is by using the standard antenna perpendicular with active antenna polarization mode to measure (as vertical polarization radiates, horizontal polarization receives), the polarised direction of active antenna is determined by finding minimum emittance position.
The present invention wraps up one layer of preservative film at the actinal surface place of active antenna, cover lid layer in central area and can reflect the film coating of laser, transmission radiofrequency signal, the laser signal that laser ranging system is launched is after reaching film coating, through reflecting back into range unit, such that it is able to the distance obtained between active antenna actinal surface place and the centre of gyration, before using radiofrequency signal to carry out phase comparing ranging, distance between each antenna to the centre of gyration is adjusted in a wave-length coverage, then radio frequency range finding is being carried out, the problem that thus can solve range ambiguity.
In conjunction with accompanying drawing, according to hereafter by the description illustrating present subject matter, other aspects of the present invention and advantage being known.
Accompanying drawing explanation
By reading the detailed description that non-limiting example is made made with reference to the following drawings, the other features, objects and advantages of the present invention will become more apparent upon:
Fig. 1 is one RF array array antenna calibrating installation structural representation of the present invention;
Fig. 2 is RF array array antenna system structure schematic diagram.
In figure: 1 is laser ranging system, 2 is thin film, and 3 is film coating.
In accompanying drawing, same or analogous accompanying drawing labelling represents same or analogous parts.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail with embodiment. Should be understood that following example are merely to illustrate the present invention not for limiting the scope of the present invention.
As it is shown in figure 1, the present invention increases laser ranging system in radio frequency test device. Five red points at region, the center of circle place namely testing equipment in the middle of four reception antennas are exactly laser emitting source.
As in figure 2 it is shown, the present invention wraps up one layer of preservative film at the actinal surface place of active antenna, cover lid layer in central area and can reflect the film coating of laser, transmission radiofrequency signal.
When finding range, the laser signal that laser ranging system is launched is after reaching film coating, through reflecting back into range unit, such that it is able to the distance obtained between active antenna actinal surface place and the centre of gyration, before using radiofrequency signal to carry out phase comparing ranging, distance between each antenna to the centre of gyration is adjusted in a wave-length coverage, is then carrying out radio frequency range finding, the problem that thus can solve range ambiguity.
In the polarised direction calibration process carrying out antenna, five laser emitting sources disposed in radio frequency test device are opened simultaneously, these five bright spots being irradiated on active antenna may determine that the reference measure line of vertically and horizontally both direction, the comparison on position is carried out with the four of antenna JIPIAN, can substantially determine whether the polarised direction of antenna meets the requirements, then re-use radio-frequency measurement method to measure, so can obtain more reliable measurement and debugging result.
