Estimation of Direction of Arrival and Doppler Frequency with Array Error
Jianwu Tao · Acta Armamentarii · 2005
When there exists general array error in uniform linear array (ULA), an estimation of the direction of arrival (DOA) and Doppler frequency for signals was proposed. The array error model of ULA was set up. Detailed analysis of ambiguous problem was presented. Unambiguous DOA and unambiguous Doppler frequencies for signals were calculated by total least squares (TLS) and maximum likelihood (ML). Simulated results show that the algorithm is valid and robust.
