Data Analysis of Static Simulating of Altitude Measuring Using Radio Altimeter

对弹载无线电高度表的测高原理进行了详细分析,并介绍某型反舰导弹使用的KGW-XX型无线电高度表海面模拟测高试验方法,给出了试验数据,并对试验结果进行了理论分析和数据仿真.模拟测高试验结果表明:该高度表可在超低空状态下提供稳定的高度数据,可以作为此导弹武器系统的高度传感器;该高度表提供的高度数据存在着较大的阶梯误差,将影响武器系统的恒高精度.通过分析模拟测高试验结果,指出了该高度表提供的高度数据存在较大阶梯误差的原因及解决途径.

The theory of missile-borne radio altimeter measuring height is analysed in detail,an approach of static simulation of altitude measurement using a KGW-XX radio altimeter installed in a target drone model is introduced,and experimental data are presented,testing results are analyzed in theory.Experimental result indicates that steady height data can be provided at ultra—low altitude by the KGW-XX radio altimeter which can be used as an altitude sensor of a tow target system,and the height data shows a bigger ladder error that affects the precision of the tow target system.The reason why ladder error exists in the height data,and an approach for reducing the ladder error are given.
