Abstract
Difference of capacitive sensor was applied to the scanning system of radar as position sensor.Working characteristics of capacitive sensor was studied and measurement circuit was designed.The linearity and static error of the capacitive sensor system was tested and calibrated.The experimental results show that the linearity of sensor reaches to 99.9 % at a limited range and it offers precision position information to radar system.
