Abstract:

A union estimation algorithm is presented to estimate DOA of CM signal and mutual coupling coefficient of array antennas. The new algorithm does not need the assistant calibration sources that directions are known and may estimate direction of actual source online. Simulation results show the accurary of the new method depends on snapshots and the direction combination and SNR of signal sources.

Key words: Array antennas, Nonlinear constraint, Error calibration
