摘要
采用注入法进行了高度表对脉冲雷达的敏感度实验,测出了高度表对脉冲雷达的敏感度。实验表明,高度表受到脉冲雷达干扰时,高度表的读数误差增大,且随着雷达干扰信号强度的增加,高度表读数误差也增大。为了研究脉冲雷达对高度表的干扰机理,介绍了高度表工作原理,分析了高度表的信号和数据处理过程。在此基础上得出如下结论:干扰使平衡检波器信号波形上出现了许多窄脉冲,这些窄脉冲使高度表误差增大,最后给出了抗干扰对策。
The injection experimentation of altimeter sensitivity to pulse radar is made,and the sensitivity is tested. The experimentation shows that interference signal of pulse radar can change the reading of altimeter, and the altimeter＇s error increases as the interference intensity does, In order to study the interference principle of pulse radar to altimeter,the work principle of altimeter is introduced,and the signal and data processing of altimeter are analyzed, Based on this, the paper come to the conclusion that many narrow pulses on the waveform generated by balance detector make the altimeter＇s error increases. In the end,the anti- jamming methods are given.
