Meaning.
At present, the detection for radar array antenna sparking fault mainly uses infrared measurement of temperature (imaging) instrument to be poised for battle with location
Son carries out temperature test or maintainer stands in antenna side, is listened by ear or the method touched, and carries out fault manually fixed
Position.But said method exists problem: one when being to use infrared measurement of temperature (imaging) instrument, after radar emission, these electronics
Equipment is exposed under strong electromagnetic transmitting, it is impossible to normally works, after waiting radar switching-off, climbs up antenna platform, the temperature measured
Number of degrees value has become inaccurate；Two be use maintainer ear listen or touch method time, owing to radar is in greatly
Power emission state, and personnel must be exposed under radiation, just it is observed that a period of time situation, therefore to the microwave radiation of human body relatively
For seriously.And in this case, in order to more be accurately positioned fault, antenna can only stop the rotation, fix an orientation and enter
Row radiation, it is difficult to omnibearing spark phenomenon is observed, when rotary joint goes wrong, causes beating in certain orientation
Fire, this Observations Means cannot detect.
During the sparking of radar generation antenna element, can be with violent sparking vibrations, bigger variations in temperature, noise source of striking sparks
The position bigger with range of temperature, there is the place of sparking fault in antenna element just.By to the location of noise source, temperature
The detection of degree, can position antenna element sparking trouble point.
