摘　　要：为满足弹载探测器的高度测量需求,对高程测量方法进行研究,在载弹中设置北斗卫星信号接收组件,利用两个北斗卫星信号来确定引信的实际对地高度,进而发出指令起爆引信主装药。其中一个北斗信号被弹载接收组件直接截获,而由同一卫星发射的另一信号则经过反射后被弹载的另一接收组件截获,通过上述两信号间传输距离与时间的差异来计算引信的对地高度。同时结合误差模型,利用最小二乘融合算法降低测高误差,提升弹载探测器的测高精度。In order to meet the requirement of altitude measurement of missile-borne detector,the altitude measurement method is studied.The Beidou satellite signal receiving module is set up in the missile,and the actual height of the warhead to the ground is determined by using two Beidou satellite signals,and then the command is issued to detonate the main charge of the warhead.One of the Beidou signals is intercepted directly by the missile-borne receiving module,while the other signal transmitted by the same satellite is intercepted by the missile-borne receiving module after reflection.The height of the warhead to the ground is calculated by the difference of transmission distance and time between the two signals.At the same time,combined with the error model,the least squares fusion algorithm is used to reduce the altimetry error and improve the accuracy of the missile-borne detector.
