Direction finding (DF) refers to the establishment of the direction from which a received signal was transmitted.
it is like estimation of the direction of a signal. it is an antennas and wave propagation problem but the estimation the direction of the signal is related with signal processing. hope i posted this topic in the right forum
try this article as a point of start (look for it at google)
SDR_in_Direction_Finding_RFDesign_0105.pdf
you can also search for DF basics, diferent implementations and solutions in the DSP field introducing the words "electronic warfare" in your google's searches. Luck!
attached one of my trials writing the MUSIC code which I could find
I think it has some errors, it gets the number of signals but the spectrum needs some revision
Hi
Try implementing the conventional beamformer (Delay and Sum) for Direction of Arrival Estimation and then go for the high resolution methods like MUSIC and ESPRIT.
Conventional methods are relatively easy to implement
