A radar extended target angle estimation method based on effective phase clustering

open access: yesThe Journal of Engineering, Volume 2023, Issue 12, December 2023., 2023
Multiple scatter points detected from extended targets in high‐resolution radar systems are often difficult to match with real target points due to uncertain factors such as clutter and system noise. To address this issue, this paper introduces the concept of effective phase and proposes a direction of arrival (DOA) angle estimation method for extended
