Background technology
Phased array weather radar has multiple receptions, transmission channel, and line amplitude, phase test are entered to it, is to develop phased
The important process of battle array weather radar.At present, respectively to receiving（Emitter）, antenna tested, this test one is that efficiency is low,
Two be receiving channel（Transmission channel）It can not be tested with the matching properties of antenna.
The content of the invention
It is an object of the invention to provide a kind of reception of phased array weather radar, transmission channel detection method and device, to solve
The efficiency that certainly traditional measuring technology is present is low and can not be to receiving channel（Transmission channel）Surveyed with the matching properties of antenna
The technical problems such as examination.
In order to realize foregoing invention purpose, technical scheme is as follows：
Phased array weather radar is received, transmission channel detection method, and its step is as follows：
Tested phased array weather radar antenna is provided opposite to an antenna diameter and is more than tested phased array weather radar antenna

Parabolic antenna feed source connects a radio-frequency signal source（Such as X-band signal source）, radiofrequency signal becomes parallel by parabola
Beam radiation is to phased array weather radar antenna, and each antenna element of phased array weather radar is received after signal, and feeding correspondence is received
Machine, the signal magnitude and phase noise of the reception of each receiver can be just tested with frequency spectrograph；
Ripple control device controls some emitter or certain several emitter to open, and by phased array antenna unit, radiofrequency signal gives off
Go, only parallel electromagnetic wave, i.e., parallel parabola antenna axle, collected by parabolic antenna feed source, be sent to frequency spectrograph；
Each emitter is separately turned on, each transmitter signal strength, phase noise can be tested respectively；Transmitting is opened in increase one by one
Machine, can be with test phase characteristic.
Phased array weather radar is received, transmission channel detection means, including an antenna diameter is more than tested phased array
The parabola antenna of weather radar antenna, be connected with parabolic antenna feed source to tested phased array weather radar launch radio frequency
One radio-frequency signal source of signal and the reception being connected with parabolic antenna feed source are tested phased array weather radar transmitting radio frequency
One frequency spectrograph of signal.
Advantages of the present invention is as follows：
1）Antenna that can be to receiving channel, receiver integration test.
2）Antenna that can be to transmission channel, emitter integration test, can not only test transmission signal amplitude, moreover it is possible to check
Whether phase is consistent.
