DOA estimation with extended sparse and parametric approach in multi‐carrier MIMO HFSWR
The Journal of Engineering, Volume 2019, Issue 21, Page 7810-7814, November 2019., 2019 To obtain a higher angle resolution of multiple‐in multiple‐out high‐frequency surface wave radar (MIMO HFSWR) for direction of arrival (DOA) estimation with a limited number of antenna sensors, multiple working frequencies are proposed to enlarge the aperture of the virtual array of the MIMO HFSWR.
