| 摘 要： | 针对现阶段以DSP为主控制器的弹载地磁测量组件体积大、造价成本高、开发难度大的问题,选用基于ARM内核的STM32F4系列单片机为主控,对地磁测量组件进行了模块化设计。通过对地磁信号的采集、放大及处理分析实现了对弹体滚转角的测量。测试结果表明组件滚转角测量误差不超过3°。组件单板尺寸减小30%以上。极大的降低了开发难度和成本,相关技术可应用于小型弹箭的简易制导。

| Abstract: | A design of geomagnetic measurement kit based on ARM core STM32F4 series microcontroller is proposed in order to solve the problems of large scale,hign cost and difficulties in developing application of the geomagnetic measurement kit based on DSPs at present.This scheme can measure the projectile roll angle by collecting,amplifying and processing the geomagnetic signal.The test results show that the measurement error of the kit is less than 3°.The single board scale is reduced by more than 30%,and it greatly reduces the difficulty and cost of developing processing.The related technology can be applied to the simple guidance of small projectiles. |
