Abstract

Simultaneous frequency and direction-of-arrival (DOA) estimation can be formulated as a 2D processing problem or as a set of coupled 1D problems. In narrow-band cases the 2D approach can be used to remove the need for frequency-DOA pairing procedures but the price can be a considerably higher computational cost. Therefore, the 1D approach a viable alternative in many applications. This paper presents an ESPRIT based technique using the multiple 1D approach. It requires few sensors, guarantees identifiability of the parameters and admits several sources on the same frequency or DOA
