Description
Technical field
It tests the speed Doppler radar vibration absorber the utility model relates to one kind, in particular to it is a kind of more for testing the speed for missile-borne
General Le radar vibration absorber design.
Background technique
Doppler speed radar is used to provide the navigation informations such as three axial velocities for inertia/satellite navigation system, to realize
Inertial navigation/doppler combined navigation function.In the course of work, based on Doppler effect, the electromagnetism based on instrumentation radar radiation
Frequency difference between wave and echo obtains velocity information, difference, that is, Doppler shift in frequency.When the ginseng of radar
After number determines, Doppler frequency fd is only related relative to the movement velocity on ground with the carrier of radar.Pass through beam antenna
Each component of obtained radar bearer rate vector is measured (i.e. along the longitudinal velocity in course, the laterally speed vertical with course
Degree and vertical speed) for navigation.
Entire Doppler speed radar is rectangular shape, and radar uses waveguide fixed antenna, and dual-mode antenna shares, antenna
Positioned at equipment abdomen, transmitting antenna emits to the ground through warbled continuous wave when work, utilizes transmitting signal and echo letter
The first harmonic of number Beat Signal through being mixed tests the speed.
It usually can be used to realize the Doppler speed radar structure of above functions mainly by antenna, high frequency assembly, power supply, letter
Number processing and the parts such as combination are received, passes through waveguide connection and composition between each component.
Since missile-borne use environment is harsh.So missile-borne Doppler radar has the following problems:
1, existing Doppler radar is all airborne use, and not conformal with carrier, and the installation space needed is larger, installation
Precision is low, seriously affects the rate accuracy of radar.And missile-borne Doppler radar space is small, rate accuracy is high.
2, under missile-borne environment, the vibration environment that Doppler radar is born is more larger, existing Doppler radar host
Interior signal processing is not suitable with the vibration environment that missile-borne is flown with combined working condition is received, and need to install vibration insulating system additional and offset body
The interference of vibration.
3, due to the precision of existing Doppler radar be by after installation accuracy and adjustment and calibration determine, if plus
Dress vibration insulating system destroys its installation accuracy.
Utility model content
It tests the speed Doppler radar vibration absorber, how general improves in view of the shortcomings of the prior art, the utility model provides one kind
Anti-jamming Ability for Radar, measurement accuracy and reliability are strangled, the demand of Doppler radar on high-speed aircraft is applicable in.

Further, the flange frame is fixed on body by screw and horizontal radial positioning pin.
The utility model has the beneficial effects that
1, the utility model uses radar and the conformal scheme of body has carried out structure design, has both realized and inertial navigation skill
Art performance associated structure technology installation accuracy requirement, and realize structure Anti-interference Design, effectively increase product can
By property, maintainability, Electro Magnetic Compatibility；
It 2, is that signal processing installs vibration insulating system additional and horizontal direction is to receive combination and install additional to subtract in complete machine internal vertical direction
Vibrating system improves the reliability of product, preferably adapts to working environment；
3, extension set and the conformal scheme of complete machine efficiently solve radar installation accuracy and miniaturization issues, reduce hardware
The complexity of equipment, and ensure that the installation accuracy with inertial navigation.
4, entire radar is compact-sized, and degree of integration is higher, is conducive to improve rate accuracy, reliability, maintenanceability,
It is also convenient for the update of radar.
