摘要: An eigenstructure-based method for direction finding in the presence of sensor mutual coupling, gain, and phase uncertainties is presented. The provides estimates directions-of-arrival (DOA) all radiating sources as well calibration gain each coupling receiving array. proposed algorithm able to calibrate array parameters without prior knowledge manifold, using only signals opportunity avoiding need deploying auxiliary at known locations. described detail, its behavior illustrated by numerical examples. >
