An Accurate Compact Processor for Mobile DF Operations

The AADF-3100 Mobile DF processor is a single channel DF system for vehicle, airborne, fixed, or shipboard use.  It is designed to work with the covert series of annular slot antennas and can cover 1 MHz to 3 GHz in 5 bands. The system uses sign wave modulation to preserve the directional intelligence of the RF signal.  These antennas are typically low profile or totally undercover.

For better gain and higher frequency coverage the AADF-3100 will also work with log periodic antenna systems that cover 600 MHz to 6 GHz in one band. 

The AADF-3100 is designed to receive primarily vertically polarized signals.

The AADF-3100 provides all power and control to the antenna system through a single control cable.  The received signal with bearing information encoded is routed to the receiver through RF coaxial cable.

The processor has RS-232 input for GPS information and interlaces this with the DF data that is sent to a computer for mapping and bearing plotting.
