The research describes the implementation approaches of a pseudo Doppler radio direction finding method based on software defined radio technology. A block diagram of an automatic pseudo Doppler software defined radio direction finder is proposed. A hardware functional diagram of specialized software architecture is offered. New schematic solution for antenna commutator and beating software synchronization is realized. For smoothing the bearing measurement of an aperiodic cyclic field based filtering procedure is proposed. By mathematical and experimental modeling a key features of a pseudo Doppler software defined radio direction finder are proved in comparison with the classical implementation: short signals bearing ability, statistical smoothing algorithms implementation convenience, simultaneous multiple frequency channels direction finding possibility, processing information simplification, flexibility and reconfigurability of radio direction finding systems. A prototype that implements the proposed approaches, circuitry design, software and algorithmic solutions is developed.
