为了实时解算弹丸滚转角,根据二维磁阻传感器测量转速的原理,设计了弹丸滚转角的实时解算算法。选用TMS320F2812作为处理器,提高了滚转角解算的实时性。进行了滚转角的解算试验和误差分析,试验结果表明,通过选择合适的试验参数,该设计能够较准确的解算弹丸的滚转角,使其误差保持在±5°以内。

For real-time calculation of projectiles roll angle, according to the principle that two-dimensional magnetic resistant sensor detecting rotation speed; a real-time algorithm for calculating projectile's roll angle was designed. The TMS320F2812 was selected as the processor for improving real-time performance of roll angle calculation. The experimentation based on this program was done and the error was analyzed. The result indicates that by selecting appropriate parameter, the roll angle can be calculated exactly and the error is kept within ±5°.
