Aimed at the problem of low elevation estimation in VHF multipath environment, a fast temporal-spatial sequential algorithm is proposed. The information in both the time domain and frequency domain is applied to improve the direction-of-arrival estimation performance. First, by utilizing the information on range and velocity, which has been achieved in tracking environment, the received data are integrated to form a single sample of the array signal vector. Then, a matrix pencil is constructed by the vector. Finally, the generalized eigen-decomposition is employed to estimate the direction-of-arrival directly. While overcoming the multipath effect, this method avoids the spectrum peak searching and reduces the computational burden. Theoretical analysis and computer simulation results demonstrate the effectiveness of the proposed method.

Key words: VHF radar, altitude measurement, multipath, direction-of-arrival, matrix pencil
