| 摘 要： | 探讨了机栽DME设备对GPS/L5接收机的电磁干扰状况.通过分析机载DMECW脉冲信号的发射功率、GPS接收机天线与DME天线之间隔离度等重要参数,计算出不同隔离度时CW干扰功率与接收机容许值之间的差异,认为GPS/L5能克服隔离度较大时的CW干扰,而隔离度较小时干扰功率超过容许值.

| Abstract: | The interference effect from airborne DME to onboard GPS/L5 receiver is introduced in this paper.Analyzing the representative values of the DME CW radiation power and the isolation between GPS and DME antennas,the gap between DME CW radiation powerand assumed L5 interference threshold for some isolation data is estimated.DME CW interference might be occurred for higher isolation,and for lower isolation these are still above the allowed threshold. |
