A Two-Stage Method for Short-Wave Target Localization Using DOA and TDOA Measurements

open access: yesIEEE Access, 2023
The ionosphere can make the short-wave source localization problem further non-linear, leading to a complicated solution process. This paper proposed a coordinated positioning algorithm based on the ionospheric virtual height (IVH) model to jointly ...
