Design of Range Adjustment Circuit for Ballistic Angular Rate Measurement Sensor
Accurate measurement of angular rate is an important means to realize the transformation of munition guidance.In view of the problem that the range of the common angular velocity gyroscope on the market can not be matched with the angular rate of rota-tion of the projectile,the output voltage of the angular velocity gyroscope is linearly amplified by an operational amplifier in order to adaptively match the angular rate of rotation of the projectile.Using high-speed flight simulation turntable on the design circuit for test demonstration,the test results show that:the designed sensor range adjustment circuit is correct,in the positive and negative full-scale test conditions,the absolute error of angular rate measurement is about 15 °,the design method has a certain value of engineer-ing applications.
