Elliptical DoA estimation & localization

, 2022
Summarization: This work puts forth elliptical direction of arrival (DoA) estimation and localization, using phase-based, narrowband measurements. The method exploits a multistatic architecture, where illuminating and receiving antennas are placed in the

Wideband DOA Estimation on Co-prime Array via Atomic Norm Minimization

Energies, 2020
This paper introduces a low complexity wideband direction-of-arrival (DOA) estimation algorithm on the co-prime array. To increase the number of the detectable signal sources and to prevent an unnecessary increase in complexity, the low dimensional co ...

Harnessing Spatial and Multi‐Criteria Decision Analysis (MCDA) to Optimize Land Suitability for Kenaf Cultivation in Kelantan: Pathways for Sustainable Economic Development

Land Degradation &Development, Volume 37, Issue 15, Page 11438-11458, September 2026.
ABSTRACT In Kelantan, entrenched land degradation and extensive idling of agricultural lands exacerbate rural poverty. Current top‐down planning often overlooks local geographic and social constraints, despite state initiatives to convert idle lands and strengthen rural livelihoods.
