Abstract :
In Multiple input multiple output (MIMO) radar, for the practical degradation performance of traditional method for 2-D direction of Arrival (DOA) estimation in the low signal to noise ratio (SNR) or in small number of snapshots environment, a 2-D DOA estimation algorithm based on propagator is proposed in this paper. The conjugate data reconstruction thought is applied to estimate the propagation operator and the rotation invariance of the propagator is used in direction matrix estimation, and then the 2-D angles information is obtained by the direction matrix, with the matrix change and structure feature, elevation and azimuth angles are automatically matched. The algorithm performs well in low SNR and limited snapshot situation. Effectiveness of the proposed algorithm is demonstrated by simulation experiment results.
