Low‐Complexity DOA Estimation: Combining VSSLMS With FFT Spectrum Estimation
Electronics Letters, Volume 62, Issue 1, January/December 2026.This letter presents a novel, low‐complexity framework for DOA estimation. The proposed method achieves a significant reduction in computational complexity—from O(ML) to O(M log L)—compared to conventional SSE methods. Crucially, as illustrated in the accompanying figure, the method maintains high estimation accuracy, outperforming standard SSE‐based ...

Robust Radar Tracking via Joint Adaptive EKF and Power Allocation Under Dynamic Clutter
Electronics Letters, Volume 62, Issue 1, January/December 2026.ABSTRACT In this letter, a joint adaptive extended Kalman filter (AEKF) and power allocation strategy is proposed for robust multitarget tracking in colocated MIMO radar systems under dynamic clutter. The unknown clutter intensity is incorporated into the measurement model and characterized by a truncated inverse gamma distribution.
