摘  要:在空降作战中,快速集结是部队的一项重要能力,能大幅提高队伍的生存率和战斗力。GPS在战斗中易受干扰无法使用。本文在禁用GPS的条件下,针对快速集结中的快速定位问题,设计一款结合无线电测向、激光测距的电子罗盘系统,该系统采用HMC5883L三轴磁阻传感器测量载体三个轴的磁场强度,采用MPU6050加速度传感器在罗盘倾斜的情况下计算姿态角对测量值进行补偿,得到方位角。利用激光测距测得行走距离,通过三角定位的方法,计算出目标信号源的具体位置,达到快速集结的目的。

Abstract: In airborne operations, rapid assembly is an important capability of troops, which can greatly improve the survival rate and combat effectiveness of troops. GPS is easily disturbed in battle and cannot be used. In this paper, an electronic compass system combining radio direction finding and laser ranging is designed under the condition of disabling GPS. The system uses hmc5883l three-axis magnetoresistive sensor to measure the magnetic field strength of the three axes of the carrier, and mpu6050 acceleration sensor to calculate the attitude angle when the compass is tilted to compensate the measured value, get the azimuth. The walking distance is measured by laser ranging, and the specific position of the target signal source is calculated by triangulation, so as to achieve the purpose of rapid assembly.

空降兵的作戰方式是空降到战场,高机动性是空降兵的特点之一。由于空降兵跳伞后,空投物资和人员着陆位置分散,散布范围非常广,设计并实现一套快速搜寻物资并快速集结的系统是必要的。国外的集结定位设备完全依赖GPS,GPS在战争状态下易受干扰,因此需要开发出GPS停用时的应急替代设备。现有的单值无线电测向设备,只能探测无线电信标的方向,无法测量距离,在实际作战中需要配合地图与指南针使用,非常不方便。

本文将MEMS传感器、电子罗盘、激光测距与RSSI技术相结合,设计了一种不依靠卫星定位的自动化测向系统,解决了空降兵跳伞着陆后快速集结这一难题。
