Capacitive encoder is a novel sensing technology developed from the traditional capacitive technique. Aiming at the high-precision testing requirement of the relative angle between the turret and its chassis, a high-precision measurement method of turret dynamic angle based on capacitive encoder was proposed. In view of the turret environment, the installation method of the capacitive angle measurement was designed and the working principle was analyzed. With the design of the mechanical structure and the subsequent circuit, the system stability and reliability of the capacitive encoder were improved. Laboratory angle calibration and field range experiments for angle measuring device were carried out. Results show that the system which obtains the function of power protection, location identification and zero-memory can meet the actual demands and the measurement accuracy is up to 60＂.
