Design and realization of portable direction-finding and communication receiver

The wireless direction-finding and wireless communication system have been widely used in civil and military fields. This paper presents a portable direction-finding and communication receiver based on amplitude comparison direction-finding system and algorithm, and demonstrates its application in a wireless communication system. It can counteract the influence to the antenna pattern caused by the hardware circuit, human body, surrounding environment and so on, and has the advantages of small size, fast measuring speed, better anti-jamming capability. Thus it can be widely used in public security, forest fire prevention, geological resources exploration and other fields.
