hi all ,
i am having an 8-antenna circular array for direction of arrival estimation , i need to calibrate the phase shift and attenuation of each antenna to a reference antenna... however i didn't know how to calculate the phase shift of antenna's..
i don't have a network analyzer so i am trying to send a sine wave from the function generator and estimate the shift on each antenna but i am getting different values each run which means that i am having something wrong , the phase shift code work fine in simulation (generating two known signal and finding the shift) but when i apply it on hardware , it doesn't work ..
any idea how to debug such problem
thanks in advance
