Özet
In foggy, cloudy and rainy weather; for the purpose of radiometric imaging; Passive MilliMeter Wave Imaging System (PMMWIS) was installed with a radiometric receiver operating at a frequency of 96 GHz which is one of the specific frequency windows for passive detection. After the installation of this system, while working, there were contractions in the motor part of the 2-axis positioner with which the parabolic reflector antenna of the PMMWIS. These contractions were mainly during upward system calibration or during normal scan of the system. Therefore, it had become necessary to make balance weights for more convenient operation. In this study; the equilibrium weights were integrated in order to synchronize the moment to the opposite direction of the parabolic reflector antenna. According to the weight and height of the parabolic reflector antenna to be mounted on the system, four different balance weights could be used. The sounds from the gears in the engine of the 2-axis positioner, indicating that the motor was contracted for every degree to be scanned (it could be 0.1 degrees to the resolution) was indicative of the deterioration of the gears in the 2-axis positioner. Consequently; the balance weights were produced and integrated into the system. As a result; the torque of the antenna was achieved and the 2-axis positioner was able to scan the view by means of PMMWIS without any contraction in the azimuth and elevation axes.
