Direct position determination of moving targets based on DOA
Electronics Letters, Volume 60, Issue 15, August 2024.This letter proposes a new DPD method for moving target based on DOA. First, using a proposed cost function, the position information is obtained from the received array signals directly, which enhances the accuracy of localization. Second, utilizing the method of successional difference the velocity is extracted, which avoid the multi‐dimensional grid
