摘要:
针对非旋或微旋弹引信第二环境力微弱和不容易识别的问题,考虑到地磁场强度的方向性,提出应用三轴磁传感器检测炮口地磁信号,获取弹丸出炮口信息,以此作为引信冗余保险激励环境信息。分析了基于地磁信号的冗余保险方法,建立了三轴磁传感器检测地磁信号的数学模型,通过对国内不同区域、不同发射情况的仿真分析,结果表明:应用弹丸出炮口的地磁信号作为弹丸引信的第二环境激励,方法可行;应用三轴磁传感器可避免单轴磁传感器敏感地磁信息的盲区问题,保证了基于地磁信号的冗余保险方法的可靠性。
Abstract:
In view of the problem that the second environmental forces are weak and not easy to be measured,a three-axis magnetic sensor is used to detect the geomagnetic field intensity on the muzzle based on the directivity of the geomagnetic field.The information is obtained when the shot leaves the muzzle,which can be used as the driving source of the fuze redundant safety machine.The method of redundant safety based on geomagnetic signal is analyzed,and a mathematic model of the three-axis magnetic sensor measuring the geomagnetic field is built.Some simulations are carried out in different regions and different launching conditions.The results show that the geomagnetic signal on the muzzle can be the second environment prompting of the fuze;the measuring blind area can be avoided by replacing a single-axis magnetic sensor with a three-axis magnetic sensor.The method can ensure the reliability of the redundant safety based on geomagnetic signal.
