Abstract :
This paper shows an implementation of a Radio Direction Finding prototype using three AoA algorithms and MIMO synchronization over a SDR platform, with a non-calibrated two element array. This algorithms were tested in three scenarios with different type of transmitted signals including baseband AM and FM sinusoidal tone and an AM modulated voice signal. The angle was estimated with a mean error below 0.3.
