Signal Subspace Reconstruction for DOA Detection Using Quantum-Behaved Particle Swarm Optimization

Rui Zhang et al.

Summary: This study proposes a DOA detection method using Quantum-Behaved Particle Swarm Optimization for signal subspace reconstruction, effectively addressing missed detection and reduced accuracy due to low SNR and snapshot deficiency. The approach improves DOA detection performance when signals have varying SNR levels and small snapshots, with results showing superior estimation performance.

Tensor-Based Reduced-Dimension MUSIC Method for Parameter Estimation in Monostatic FDA-MIMO Radar

Tengxian Xu et al.

Summary: This paper investigates a tensor-based reduced-dimension multiple signal classification (MUSIC) method for target parameter estimation in FDA-MIMO radar. The method optimizes the effectiveness and stability of parameter estimation, reduces computation complexity, and overcomes performance degradation in small samples or low SNR by capturing the multi-dimensional structure of the received signal using tensors.

A TOA-DOA Hybrid Factor Graph-Based Technique for Multi-Target Geolocation and Tracking

Lei Jiang et al.

Summary: This article proposes a new distributed sensors-based multi-target geolocation and tracking technique, which combines two factor graph models to address positioning and tracking problems. With the sensor association technique, the accuracy of multi-target geolocation and tracking performance can be significantly improved, especially in 3D scenarios where complexity is reduced through plane projections.
