Description
Technical field
The present invention relates to Multipactor detection field, and in particular to a kind of to realize that Multipactor is examined using vector analysis
The apparatus and method of survey.
Background technology
Multipactor is also known as multipactor, refers under vacuum, and free electron is in additional radiofrequency field
Acceleration under, the secondary and multiplier effect that are excited between two metal surfaces or on single dielectric surface, be a kind of
Vacuum resonant discharge phenomenon, it is a highly important factor for influenceing space electronic equipment dependability.
Multipactor is occurred mainly in the radio frequency, microwave, millimeter-wave systems of spacecraft.It is normal in space orbit
The spacecraft of work can be by outside energetic plasma, high vacuum environment, self structure size, frequency transmission signal and power etc.
The influence of factor, multipactor (Multipactor) is produced, occur disliking microwave system gain decline, transmission performance
Phenomena such as change, signal noise increase, make microwave system cisco unity malfunction, or even the catastrophic failure thoroughly to fail occurs.Certain
In the case of kind, micro discharge phenomenon can cause the outlets such as the dielectric material of microwave device part, bonding agent, form local low vacuum bar
Part, at this moment microwave electric field may ionize the gas molecule of low vacuum environment, produce power disruption, the low pressure such as arc discharge is put
Electrical phenomena, caused high temperature dense ionization effect can burn out microwave system, and working life terminates in advance, make spacecraft occur thoroughly losing
The catastrophic failure of effect.Therefore Multipactor detection experiment is carried out to ensureing that the in-orbit normal operation of spacecraft is particularly significant.
Now with Ku, Ka wave band, or even the HT such as V-band, E wave bands (high flux) communications, the application of repeater satellite technology
With development, traditional measuring technology has been not suitable for the Multipactor detection of high band millimeter wave loaded components, has been badly in need of breaking through
Tradition, highly efficient, reliable, high sensitivity the detection technique of use.It is main at this stage use before to/backward power zeroing method,
Transmission and reflected signal are tuned into the anti-phase zeroed signal of constant amplitude by way of amplitude modulation, phase modulation, with frequency spectrograph or other similar
Whether equipment indirect monitoring reflected signal amplitude and phase change.
Transmission signal and reflected signal through great power bidirectional determine coupling and are coupled out a part in proportion to be used for signal monitoring, positive and negative
It is divided into two-way in zeroing unit to coupled signal：Export all the way to power meter, monitor positive mean power, positive peak value respectively
Power, reverse mean power；Another way enters zeroing passage and returned to zero, and zeroed signal frequency spectrum is monitored with frequency spectrograph.At this stage
The principle that returns to zero is as shown in figure 1, positive coupled signal is divided into two-way in zeroing unit by 3dB electric bridges：All the way through power splitter again

Reduce the sensitivity of Multipactor detection.
2nd, balancing controls frequency range it is narrow-across band broadband balancing controls realization, it is necessary to by switch realize frequency range select
Select.
3rd, directly perceived-zeroing method is not to be adjusted transmission and reflected signal by way of amplitude modulation, phase modulation to the detection of width phase change amount
The zeroed signal anti-phase into constant amplitude, whether occurred with frequency spectrograph or other same category of device indirect monitoring reflected signal amplitudes and phase
Change, it can not directly detect the width phase change amount of reflected signal.
