The waveguide excitation detector has the advantages of high detecting efficiency and accuracy in speed measuring.
Description
Technical field
The invention belongs to electronic information technology, specifically a kind of waveguide excitation detecting device.
Background technology
Because the application popularization rate of velocity radar on China's road traffic is increasingly high, the fast development that has brought the velocity radar detector.
The velocity radar detector is used to the frequency of operation of velocity radar and these two the key technical indexes of rate accuracy are carried out regular detection evaluation, and is in proper working order to guarantee velocity radar.Conventional implementation is: when the testing frequency; Feed Horn input end at velocity radar detector antenna connects the waveguide excitation head with flange, with concentric cable the excitation joint of waveguide excitation head and the frequency detecting port of velocity radar detector is connected; When detecting rate accuracy, at the Feed Horn input end of velocity radar detector antenna, connect the waveguide detecting head with flange, with concentric cable the detection joint of waveguide detecting head and the rate accuracy detection port of velocity radar detector are connected.When twice test conversion, need union piece of artificial replacing such as waveguide excitation head or waveguide detecting head, both are test job frequency and rate accuracy simultaneously.
Summary of the invention
In order to overcome the deficiency of above-mentioned prior art; The object of the present invention is to provide a kind of waveguide excitation detecting device; Waveguide excitation head and waveguide detecting head are united two into one; Make this device have the function of waveguide excitation head and waveguide detecting head simultaneously; After this waveguide excitation wave detector is applied on the velocity radar detector, only need need not change the detection that any device just can carry out frequency of operation and these two important technology indexs of rate accuracy of velocity radar simultaneously, have the high and characteristic of accurate that tests the speed of detection efficiency through once connecting.
To achieve these goals; The technical scheme that the present invention adopts is: a kind of waveguide excitation wave detector; Form by ring flange, excitation adapter assembly, excitation joint installation base, wave-guide cavity wave, waveguide end cap, detection adapter assembly and detection joint installation base, excitation adapter assembly and detection adapter assembly have been installed on the wave-guide cavity wave simultaneously.
Excitation adapter assembly on the described wave-guide cavity wave and detection adapter assembly be not in same direction.
Excitation adapter assembly on the described wave-guide cavity wave is horizontally disposed with, and the detection adapter assembly vertically is provided with.
Connected mode between described ring flange, excitation joint installation base, detection joint installation base, waveguide end cap and the wave-guide cavity wave is welding.
Described excitation adapter assembly makes and is screwed on excitation joint installation base.
Described detection adapter assembly makes and is screwed on detection joint installation base.
When the present invention installed and used: it was connected to the Feed Horn input end of velocity radar detector antenna through ring flange; Through concentric cable the excitation joint of waveguide excitation wave detector and the frequency detecting port of velocity radar detector are connected; Through concentric cable the detection joint of waveguide excitation wave detector and the rate accuracy detection port of velocity radar detector are connected.
The invention has the beneficial effects as follows:
This waveguide excitation wave detector system unites two into one waveguide excitation head and waveguide detecting head, makes this device have the function of waveguide excitation head and waveguide detecting head simultaneously.Waveguide excitation head and waveguide detecting head are united two into one, make this device have the function of waveguide excitation head and waveguide detecting head simultaneously.After this waveguide excitation wave detector is applied on the velocity radar detector; Only need need not change the detection that any device just can carry out frequency of operation and these two important technology indexs of rate accuracy of velocity radar simultaneously, can increase substantially the work efficiency of velocity radar detector through once connecting.
This excitation wave detector belongs to electronic information technical field, can be applicable on the product that need carry out the detection of frequency detecting and rate accuracy simultaneously.
