摘　　要：讨论了外场移动条件下多径信道的一种实时测试方法,并通过搭建的系统测试了实际外场的信道分布情况。该方法抗干扰性强,具有低功耗、精度高、实时性强的优点。实测结果表明基于该方法搭建的测试系统能够有效地测试外场多径信道的分布情况,并能够持续反映多径信道的变化情况。We have discussed the real-time method of multi-path measurement in mobile condition in this paper, and have tested the multi-path distribution of the practical field based on multi-path testing system. This method is good in anti-interference with precise accuracy and good performance of real-time. The filed test result shows that the multi-path testing system based on this method is efficient for the field test of multi-path channel, and can continuously show the variation of the multi-path channel.
