Abstract EN
Each element in the conformal array has a different pattern, which leads to the performance deterioration of the conventional high resolution direction-of-arrival (DOA) algorithms.
In this paper, a joint frequency and two-dimension DOA (2D-DOA) estimation algorithm for conformal array are proposed.
The delay correlation function is used to suppress noise.
Both spatial and time sampling are utilized to construct the spatial-time matrix.
The frequency and 2D-DOA estimation are accomplished based on parallel factor (PARAFAC) analysis without spectral peak searching and parameter pairing.
The proposed algorithm needs only four guiding elements with precise positions to estimate frequency and 2D-DOA.
Other instrumental elements can be arranged flexibly on the surface of the carrier.
Simulation results demonstrate the effectiveness of the proposed algorithm.
