Direction-Finding Technology of Aliased Sources Based on Pattern Division of Array Data
2021 2nd Information Communication Technologies Conference (ICTC)(2021)
摘要
In this paper, an idea of pattern division based on array received data is proposed. First, using energy searches, pattern division, source number estimation, and data updates, the array received data is divided into three modes: independent narrowband data, wideband data, and aliasing narrowband data. Then, a judgment matrix is constructed using the orthogonality of the direction vector with the ...
