Description
Technical field
The present invention relates to radio frequency simulation field, specifically a kind of radio frequency array antenna calibrating installation.Main function is
In conjunction with laser measurement, auxiliary improves a kind of device of array antenna mechanical location calibration accuracy from position, angle, distance.
Background technology
Radio frequency Guidance and control Semi-Physical Simulation Test System is developed the important emulation in verification process as air defence missile and is put down
Platform, confidence level height are a links for being most people's care, which has to be the development and verification of guided missile
Reliable, believable simulated environment is provided, so as to realize the mould true to nature for carrying out air defence missile whole firing process in laboratory
It is quasi-.And radio frequency array antenna system is then very important component part in the set emulation platform, its function is simulated missile
In the complex electromagnetic environment that outfield will actually face, it may be said that the realistic simulation precision of the system will influence entire emulation platform
Confidence level will not know where to begin to the HWIL simulation of air defence missile if ideal simulation precision cannot be provided yet.
Therefore in the process of construction of radio frequency Guidance and control Semi-Physical Simulation Test System, there are one extremely important steps
Being accurately positioned and calibrating for mechanical location exactly is carried out to radio frequency array antenna system.The calibration process is typically to be penetrated using a set of
Frequency calibrating installation carrys out the radio-frequency radiation signal of receiving array antenna, and by carrying out the measurement on position than equivalent way.But
It finds in actual application, if still having some shortcomings only with the method that radiofrequency signal measures, is surveying
It can be influenced by the actual test environment in darkroom during examination, wavelength is longer to easy to produce what Range Profile obscured in ranging
Problem.Also, in the radio frequency array in face of calibrating larger darkroom and a greater number electromagnetic horn composition, due to can not be fast
Speed accurately determines wavelength distance, and huge workload can be increased again by being positioned to radio-frequency antenna mechanical location.
Invention content
It is fuzzy to solve the problems, such as to easy to produce Range Profile in ranging, the present invention is intended to provide ranging speed can be improved in one kind
Degree, a kind of accurate radio frequency array antenna calibrating installation for determining wavelength distance.
A kind of radio frequency array antenna calibrating installation provided by the invention, including radio-frequency radiation signal receiver, it is described to penetrate
Radio-frequency radiation signal receiver includes reception antenna, and the antenna calibration equipment further includes and is calibrated radiating antenna polarization mode
Perpendicular standard antenna installs laser ranging component, the laser ranging group on the radio-frequency radiation signal receiver
Part includes laser emitting source, film and the film coating for capableing of reflection laser and transmission radiofrequency signal, in the RF array being calibrated
It is surrounded by the film at the mouth face of array antenna, the film coating is covered in the radio frequency array antenna central area being calibrated.
The work of radio frequency array antenna system position calibration is the principle of interferometer of being concerned with based on width.To ensure target antenna side
The centre of gyration of turntable can be accurately directed toward to figure axis（That is the centre of sphere of front）, may be used and calibrated than width mode；For
The calibration to each channel radiation signal phase equalization of aerial array is completed, realizes and school is carried out to the apparent Angle Position for synthesizing target
Standard may be used than phase mode.
The polarisation angles measurement of radio frequency array antenna system is by using the mark perpendicular with radiating antenna polarization mode
Quasi- antenna measures（If vertical polarization radiates, horizontal polarization receives）, by finding minimum radiation energy position come really
Determine the polarization direction of radiating antenna.
The present invention wraps up one layer of preservative film at the mouth face of radiating antenna, and in central area, one layer of covering can reflect sharp
Light, the film coating for transmiting radiofrequency signal, the laser signal of laser ranging system transmitting is after reaching film coating, by reflection
Range unit is returned to, so as to obtain at radiating antenna mouth face at a distance between the centre of gyration, is carried out using radiofrequency signal
Before phase comparing ranging, each antenna to the distance between the centre of gyration is adjusted in a wave-length coverage, is then being carried out
Radio frequency ranging can thus solve the problems, such as range ambiguity.
Other aspects of the present invention can be understood according to the description that present subject matter is hereafter illustrated by way of example in conjunction with attached drawing
And advantage.
