Spatial Resolution of Polarized Electromagnetic Field Sources via the Nonquadratic Regularization Method

摘要

The problem of radio radiation source localization is analyzed via the maximum-likelihood method with and without allowance for the polarization of incident waves. It is shown that the direction-finding surface normalization is an important condition. Correct normalization expressions for the time-averaged direction-finding surface have been derived via the nonquadratic regularization method. The numerical simulation results indicate that this method is superior to traditional high-resolution methods in efficiency.
