Simulations and tests of Source tracking using Goniopolarimetry method

The goniopolarimetry algorithm allows simultaneous direction finding and polarization measurement of incoming radio sources. In our case, we have done simulations and preliminary tests on 300 MHz set up, where we have designed three mutually orthogonal active monopole array antennas and the received signals are fed to the back end receiver to be digitized and correlated. Using those auto and cross-correlated parameters, along with calibrated receiver antenna parameter and receiver system co-ordinates, the gonio-poraimetry algorithm can continuously provide source direction and polarization. This whole set up has been simulated using Cadfeko and Matlab. The simulations gave us good results with maximum error of 5%.
