多通道电离层斜向探测系统的接收通道设计与实现

Design and implementation of receiving channel of multi-channel ionospheric oblique detection system

为了拓展传统单通道电离层斜向探测系统的功能,依据数字化短波接收机理论构架了一种多通道(五通道)电离层斜向探测系统的接收通道。文中着重介绍了接收通道的设计与实现。相对于传统的电离层探测系统,该系统在实现对电离层的常规探测时,可以通过阵列天线获取来波信号的波达角信息。实验结果证明了该系统接收通道设计的可靠性与实用性。

In order to expand the function of the traditional single.channel ionospheric oblique detection system,a receiver channel of a multi . channel ionospheric oblique detection system is constructed on the basis of theory of digital shortwave receiver. The design and implementation of the receiving channel are introduced emphatically. In comparison with the traditional ionospheric detection system,the proposed system can obtain the direction of arrival information of the receiving signal through the array antenna while performing the normal detection for the ionosphere. The experimental results prove the reliability and practicability of the designed receiver channel of the system.
