| Abstract(in English) | In recent years, much attention has been paid to DOA estimation using a compressed sensing technique. We have studied a DOA estimation method of multi-band signals with frequency characteristics. Using multi-band signals, we can achieve higher probability of correct estimation that using single-band signals and estimate more waves than the number of antenna elements. The half-quadratic regularization (HQR) method is a technique to solve a linear programming problem of the compressed sensing technique. In this paper, we study dependence property of three parameters in the HQR method for probability of correct estimation and obtaine adequate values of the parameters. |
