Application of Wireless Direction-Finding Communication in Target Searching

In connection with these aviation tests in the field, which need to search landing positions, a simple direction detection system for target in the field is proposed. It based on wireless direction-finding communication. The advantage of the application wireless direction-finding in the target searching is analyzed. The hardware and software of the system are described. Wireless field intensity character is analyzed and distributing is calculated under considering practical application environment. The system is proved feasible by the test in the open air.
