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.
A detailed analysis of the altimetry principle of the on-board radio altimeters and the introduction of the KGW-XX radio altimeter sea surface altimetry test method used in a certain anti-ship missile are given. The experimental data are given and the test results are carried out Theoretical analysis and data simulation.The simulated altimeter test results show that the altimeter can provide stable altitude data in the ultra-low altitude state and can be used as the height sensor of the missile weapon system. The altimeter provides a large The step error will affect the constant precision of weapon system.Through analyzing the results of simulated altimeter test, the reasons and solutions to the large step error of the altitude data provided by the altimeter are pointed out.
