| Abstract: | The working principle,structure and application of earth magnetic field sensors in bullets test system are introduced. Aimed at the specificity of bullets test, a bullets test system based on thin film coil earth magnetic field sensors is designed. The advantages of this system are that the error does not accumulate with time, high reliability and fast response, etc. The working principle and hardware structure of bullets test system and signal conditioning circuit of the thin film coil earth magnetic field sensors are briefly described. Through the cartridge testing,it validates that this earth magnetic bullets test system can accurately measure the actual flight parameters of acceleration and rotational speed. |
