Abstract


In recent years, with the rapid development of microelectronic technology, modern sensor technology, computer technology and related technology in the continuous application of new weapons and conventional ammunition was given a new vitality . The flying missile attitude information whether it is the design of the airframe , aerodynamics and ballistic institutional conduction have important significance , flying missile attitude information real-time measurements become important research topics . The topic to the live firing of the missile body of a model experiment as application background , design a missile attitude measurement system based on the three - axis magnetoresistive sensor program . The sensor characteristics analysis , The attitude information solver algorithm research , completed a test of a prototype system hardware and software design , experiments were carried out using experimental prototype system design , and live- data analysis . Including the following : (1) analysis of a common attitude measurement sensor characteristics , the basic theory of the geomagnetic field and the reference model demonstrated the advantage of the geomagnetic detection based on magnetoresistive sensors for missile attitude measurement . (2) elaborate missile attitude measurement involves the coordinate system conversion, attitude algorithm is derived mathematical model , focusing on the attitude angle using iterative correction process is derived . ( 3 ) design of a two - axis magnetoresistive sensor with single-axis magnetoresistive sensor orthogonal combination of three-axis measurement of the program , combined with the electronic theodolite , optical encoder designed turntable experiment hardware systems , system error sources the analysis and compensation . (4) for the turntable experiments, and the experimental platform Lee to verify the effect of the error compensation . Live- data analysis , and simulation of the the projectile flight roll angle is zero discriminant drift measurement based on magnetoresistive sensor , there is a need for further research and its value .
