Joint Signal Frequency and 2-D DOA Estimation Based on Space–time Processing Approach
In this paper,we present a space-time algorithm to estimate the carrier frequency,azimuth and elevation angles of multiple independent sources based on arbitrary array.The algorithm transfers the observed data from space domain to 2-D space-time domain by exploiting the cross-correlation of the array outputs,constructs space-time cross-correlation matrixes.The algorithm only needs three guiding sensors,and using 2-D ESPRIT can estimate carrier frequency,azimuth and elevation angles of multiple independent sources which have different carrier frequency.The simulation results show the effectiveness of the method.
