Dr. Henning Paul DC4HP: A Coherent Multi-Antenna Shortwave Receiver with Application in Direction Finding
The "Foursquare" antenna is well known in the amateur radio community for its directivity while at the same time being reconfigurable for its main direction by mechanically switching electrical phase shifters. In this talk, the author presents a SDR-based phased array for shortwave reception using a square antenna constellation. Here the switching of the phase shift takes place in software and thus allows beamforming into different, finely controllable directions simultaneously. The main hardware components, the interfacing using an affordable FPGA board and the software interface to GNU Radio will be presented as well as exemplary practical results proving the feasiblity of the approach.
The SDRA is an all day conference on Software Defined Radio and Digital Signal Processing.
