弹载无线电高度表测高能力拓展方法研究与应用*

摘要

The performance of altimeter decides the control qauality of missile portrait trajectory ,and influences the ve‐racity of flight altitude and the flight safe .This dissertation elaborates main factors determining measure performance ,and proposes the methods and realization way advancing the measure performance .Based on the engineering practice ,we refits and designs some altimeter's control sectors and adapts and optimizes the critical parameters such as receiver pass‐band and characteristics of frequency‐detecting . It is shown this methods can double the altitude measure range increasing the equipment's use value ,and fulfils the need of enhancement of the trajectory feature .%高度表的测高能力决定了导弹纵向弹道的控制品质，影响导弹飞行高度的准确性和飞行安全。论文详细分析了决定高度表测高能力的主要因素，提出了拓展高度表测高能力的基本方法和实现途径，结合工程实践完成了量程拓展型高度表控制环节的改装设计以及接收机通频带、鉴频特性等关键参数的调整与优化。实验结果表明，该方法使该型高度表的量程增加了一倍以上，提升了装备的使用价值，满足了导弹弹道形态拓展的需求。
