Detailed description of the invention
Fig. 1 is the principles of the present invention schematic diagram.
1. constant-temperature crystal oscillators in figure, 2 power splitters, 3.1GHz dressing spectrum generator, 4.8GHz dressing spectrum generator,
5.1GHz phaselocked loop, 6. receive amplifying unit, 7. receiving channels, 8. control units, 9. frequency synthesizer units.
Specific embodiment
Constant-temperature crystal oscillator (1) generates reference signal and is divided into three road signals through power splitter (2) function, is sent respectively to 1GHz and is combed
Adornment composes generator (3), 8GHz dressing spectrum generator (4) and 1GHz phaselocked loop (5)；1GHz is divided into three road signals through power splitter function,
It is sent respectively to receiving channel (7) and exciting unit as LO2 local oscillation signal, is in addition directly exported as DDS clock signal all the way；
8GHz dressing spectrum generator obtains the radiofrequency signal of 9GHz after being mixed with 1GHz phaselocked loop, and function divides two-way to make after filter and amplification
For the LO1 local oscillation signal of receiving channel and exciting unit.
The intermediate-freuqncy signal that the frequency that exciting unit generates DDS is 180MHz enters hilted broadsword by uppermixing, filtering, amplification
Commutator, signal through isolator after attenuator as calibration signal by exporting all the way；In addition pass through annular after amplifying all the way
Device is exported as the pumping signal of X-band microwave signal source module.
Frequency synthesizer unit (9), the radiofrequency signal that two-way receiving channel sends feeder line pass through numerical control after filter filtering
Attenuator realizes that STC function, radiofrequency signal pass through the intermediate frequency letter for obtaining 180MHz after filtering, amplification after down coversion twice
Number, two-way intermediate-freuqncy signal is exported through wave filter to A/D after coupling two-way monitoring signals respectively.
The major function of control unit (8) has two parts, first is that the Serial Control code to come from signal processor is carried out
Decoding, then parallel transmission gives corresponding receiving channel, completes the control to channel gain and timing；Second is that each X-band microwave
Signal source module reports therefore inspection signal is summarized and is reported, and shows malfunction by panel malfunction indicator lamp.
