Shafting Design and Precision Measurement of Instrumentation Radar Antenna Pedestal

According to the characteristics of precision instrumentation radar, the azimuth shafting and elevation shafting of two dimensional antenna pedestal are designed, and the influence of shafting precision on the angle error of the radar measurement is analyzed. Then, the factors that affect the perpendicularity of azimuth axis and the perpendicularity of azimuth axis and elevation axis are analyzed. The error of each factor is numerically distributed and accurately controlled by manufacturing and assembling, so as to meet the requirements of the total error allocation index. Finally, the precision measurement method of azimuth shafting and elevation shafting is designed. The measurement data are obtained by comparing the theoretical precision distribution value and the measured data, which proved the feasibility of the theoretical calculation and the measurement method.
