Abstract

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°.

Key words： geomagnetic detection; roll angle; magnetic resistant sensor; real-time calculation
