提出了某场区室外典型场景的无线信道测试方法及其信道传播特性，主要采用扩频滑动相关算法，对试验场区附近的办公楼外的2.4 GHz频段以及场区的低频段（1.5 GHz）和高频段（4 GHz）共2个场景、3个典型应用频段进行了实际测试，并通过离线的数据处理方式，给出了不同环境下对应不同通信应用频段的信道传播特征，旨在为今后该试验场区开展通信试验任务前的场景选址提供参考。

The channel propagation characteristics and test method for wireless channels in a typical scene are presented in this paper. The spread spectrum sliding correlation algorithm was adopted to test the typical application frequency bands at 2.4 GHz outside the office building near the experiment site area,and the intensity of low-frequency band at 1.5 GHz and high-frequency band at 4 GHz in the experiment site area. The channel propagation characteristics corresponding to different commu-nication application spectrum in the test area are given through the offline data processing mode for providing a reference for the scene site selection before the communication test task is carried out in this test site area.
