Sensor Deployment Optimization for Passive TDOA Localization Under Unknown Drift Distribution
Zhenxing Zhang, Tianxian Zhang, Zerui Zhang +2
This paper investigates how to deploy sensors offline to provide robust passive TDOA localization accuracy across the entire region of interest (ROI) when their positions are subje…
An Adaptive Balance Search Based Complementary Heterogeneous Particle Swarm Optimization Architecture
Zhenxing Zhang, Tianxian Zhang, Xiangliang Xu
A series of modified cognitive-only particle swarm optimization (PSO) algorithms effectively mitigate premature convergence by constructing distinct vectors for different particles…
A Dual-Channel Particle Swarm Optimization Algorithm Based on Adaptive Balance Search
Zhenxing Zhang, Tianxian Zhang
The balance between exploration (Er) and exploitation (Ei) determines the generalization performance of the particle swarm optimization (PSO) algorithm on different problems. Altho…
Maximum Correntropy Value Decomposition for Multi-agent Deep Reinforcemen Learning
Kai Liu, Tianxian Zhang, Lingjiang Kong
We explore value decomposition solutions for multi-agent deep reinforcement learning in the popular paradigm of centralized training with decentralized execution(CTDE). As the reco…
WRFRFT-based Coherent Detection and Parameter Estimation of Radar Moving Target With Unknown Entry/Departure Time
Xiaolong Li, Zhi Sun, Tianxian Zhang +3
A moving target may enter a radar coverage area unannounced and leave after an unspecified period, which implies that the target's entry time and departure time are unknown. In the…
Antenna Deployment Method for MIMO Radar under the Situation of Multiple Interference Regions
Tianxian Zhang, Jiadong Liang, Yichuan Yang +3
In this paper, considering multiple interference regions simultaneously, an optimal antenna deployment problem for distributed Multi-Input Multi-Output (MIMO) radar is investigated…
Optimal Deployment of Multistatic Radar System Using Multi-Objective Particle Swarm Optimization
Yichuan Yang, Tianxian Zhang, Wei Yi +4
We consider an optimization deployment problem of multistatic radar system (MSRS). Through the antenna placing and the transmitted power allocating, we optimally deploy the MSRS fo…
MIMO OFDM Radar IRCI Free Range Reconstruction with Sufficient Cyclic Prefix
Xiang-Gen Xia, Tianxian Zhang, Lingjiang Kong
In this paper, we propose MIMO OFDM radar with sufficient cyclic prefix (CP), where all OFDM pulses transmitted from different transmitters share the same frequency band and are or…
IRCI Free Range Reconstruction for SAR Imaging with Arbitrary Length OFDM Pulse
Tian-Xian Zhang, Xiang-Gen Xia, Lingjiang Kong
Our previously proposed OFDM with sufficient cyclic prefix (CP) synthetic aperture radar (SAR) imaging algorithm is inter-range-cell interference (IRCI) free and achieves ideally z…
OFDM Synthetic Aperture Radar Imaging with Sufficient Cyclic Prefix
Tian-Xian Zhang, Xiang-Gen Xia
The existing linear frequency modulated (LFM) (or step frequency) and random noise synthetic aperture radar (SAR) systems may correspond to the frequency hopping (FH) and direct se…
