Abstract
A novel rotational invariance technique for blind estimates of direction of arrival (DOA) and Doppler frequency with unknown array manifold due to array sensor uncertainties is proposed, taking Doppler frequency difference between a successive pulses as rotational parameter. The effectiveness of the new method is confirmed by computer simulation. Compared with the existing 2-D DOA-frequency estimate techniques, the computation load of the proposed method can be saved greatly.
