Abstract :
The joint estimation of frequency and 2D-DOA of signal by two l-shape arrays(TLSA) based on Propagator Method(PM) was proposed. According to the feature of TLSA, 2D-DOA can be estimated effectively, and through analysis of PM, the estimation of frequency can also be obtained. The pairing of frequency and 2D-DOA can be realized automatically. Simulation results indicate that the proposed method takes on good performance in both estimation accuracy and automatic pairing. Besides, when SNR is low, the performance is excellent.
