无线电高度表静态模拟测高试验结果分析

介绍某型拖靶使用的KGWXX型无线电高度表静态模拟测高试验方法，给出了试验数据，并对试验结果进行了理论分析。静态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，可以作为某型拖靶系统的高度传感器；该高度表提供的高度数据存在着较大的阶梯误差，将影响拖靶系统的恒高精度。通过分析静态模拟测高试验结果，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。

Data Analysis of Static Simulating of Altitude Measuring Using Radio Altimeter

An approach of static simulation of altitude measurement using a KGW-XX radio altimeter installed in a target drone model is introduced, experimental data are presented, and testing results are analyzed in theory. Experimental result indicates that the KGW-XX radio altimeter can provide steady height data at ultra-low altitude, so it 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.
