Abstract


In order to accurately complete the navigation task , ie, correctly guide the flying body along a predetermined route in time to reach the destination , the flight attitude parameters in real - time is an essential part of the . Spin missiles , for example , the roll angle is one of the important parameters to describe the status of their flight , in real-time to get the roll angle information can provide an important basis for the missile 's attitude control and navigation . However , due to the high spin missile roll rate , making the range and accuracy of the rate gyro can not meet the requirements , the article magnetoresistive sensor instead of the normal rate gyro to complete projectile roll angle measurement . Firstly, the background and significance of the research , the research status at home and abroad , a brief introduction ; theoretically derived mathematical model roll angle calculation and determine the magnetoresistive sensor is installed on the missile body ; then highlights the measurement system hardware and software design . Hardware design , the overall design of the program , and then discussed in detail the design of the various modules ; software design , the overall design process , then were introduced to complete the function of the lower machine and host computer program each module design method; Next, the analysis of the measurement system in the presence of various errors and through software algorithms to compensate for the error , thereby improving the system accuracy . Finally, the use of optical encoder on the performance of the measurement system designed to detect test to verify the feasibility of a magnetoresistive sensor projectile roll angle measurement solutions .
