direction finding, whereby each antenna in an array is sampled in sequence so as to simulate a rotating effective antenna. As the effective antenna is steered toward and away from the radio source, a Doppler shift is introduced. The resulting FM signal has directional information

Direction of the incoming sound signal is then determined by vector processing using time differences and known shape of the microphone array. These stages will run on the ZYNQ's Artix-7 FPGA subsystem. Linux environment will be used for GUI and a satellite map showing the direction of the source.

true_true_direction = true_true_direction*0.9+source_direction*0.1; And if you want to react to a specific volume, then just sum the 3 microphones together and compare that to some trigger value. The mean value of the microphones would be their sum divided by 3, but you don't need to divide by 3 if you increase the trigger value by a factor 3.
