Application

This DF system is portable, easy to install, suitable for border, harbor, coast, airport, stations and urban areas where have complex electromagnetic environment and more co-frequency interference.

1. arbitrary switching on super-resolution array direction finding / correlation interferometer direction finding, direction finding and timeliness requirements of         the same frequency signal.

2. separating signals at the same frequency, strong anti-reflection and multi-path effects, and adapting to the urban environment.

3. DF frequency covers up to 6GHz.

4. With compact size, light weight, taking no more than 1 minute to install by one single person.

5. Vehicle-mounted direction finding by expanding accessories, without extra space occupied.

6. Integration of antenna array and monitoring direction finder.
