N2 - It is well known that the presence of non-circular signals can provide extra degrees of freedom for a sensor array system, which can then be exploited for improved performance. Recently, by exploiting the non-circularity information and the difference and sum co-array concept, a new approach was developed for direction of arrival estimation in the presence of a mixture of circular and noncircular signals. In this paper, the problem is reformulated and a new algorithm is developed for direction finding under the same conditions. As shown by extensive simulation results, the so-called improved MUSIC (IMUSIC) can achieve a better performance than the existing ones.
