Traditional networked radar fusion technology adopts an open-loop signal processing manner, in which multiple nodes independently detect or track target first, and then send their raw data processed measurements to the center for state estimation. In such a working each sensor operates within predetermined rules, fixed transmit receiving mode changeable tracking environment, thus will definitely cause insufficient use of its limited resource. Resource allocation (RA) has emerged as promising exploit resource more efficient way by allocating available parameters w.r.t. collaboratively view fused performance. The goal this paper is provide brief overview RA methods network. We mainly investigate existing works divide them into two types, namely quality constrained type performance driven type. Solution techniques both types appeared literatures are also summarized. Finally, some potential future research directions field discussed.

This paper presents an efficient information-theoretic sensor management method to maximize the performance of passive multi-sensor system for multi-target tracking. We model state as a generalized labeled multi-Bernoulli (GLMB) random finite set and formulate dynamic selection process partially observable Markov decision (POMDP). The optimization objective is maximum information gain obtained from observed data, which measured by Cauchy-Schwarz divergence. accomplished with two main technical innovations. first tractable decomposed POMDP based solution, in informative sensors are selected sequentially candidates on second novel dual-stage fusion strategy iterated-corrector GLMB filter. Since uncertainty generally large, scheme can be greatly influenced order updates. To fix this problem, ranked divergence selection, followed update. For fusion, effect poor weakened that better enhanced. Simulation studies demonstrate effectiveness efficiency proposed challenging tracking scenarios.

This article introduces an accurate, robust, and efficient direct yaw-moment control (DYC) architecture for four-wheel independently actuated (FWIA) autonomous vehicles via the nonsingular terminal sliding mode (NTSM) method. To improve DYC performance of FWIA path tracking under critical maneuvers, a more accurate vehicle lateral dynamics model that considers tire nonlinear mechanics combined conditions is established first. On this basis, method based on phase plane theory introduced to analyze stability, two optimal external yaw moments are calculated by using NTSM algorithm takes reference rate sideslip angle as objectives, respectively. Then, moment finally applied weighting values, weight coefficient optimized in real time particle swarm optimization according instability analysis results.

To meet the requirements of safety, concealment, and timeliness trajectory planning during unmanned aerial vehicle (UAV) penetration process, a three-dimensional path algorithm is proposed based on improved holonic particle swarm optimization (IHPSO). Firstly, terrain threat, radar detection, time in process UAV are quantified. Regarding threats, echo analysis method cross section (RCS) spatial situation to quantify concealment penetration. Then structure-particle (PSO) from three aspects. First, conversion ability search strategy enhanced by using system clustering information entropy grouping instead random constructing state switching conditions fitness function. Second, unclear setting iteration numbers addressed spacing create termination condition algorithm. Finally, optimized intended building predictive control model IHPSO for simulation verification. Numerical examples show superiority over existing PSO methods.

This article considers the 3-D collaborative trajectory optimization (CTO) of multiple unmanned aerial vehicles to improve multitarget tracking performance with an asynchronous angle arrival measurements. The predicted conditional Cramér–Rao lower bound is adopted as a measure predict and subsequently control error online. Then, CTO problem cast time-varying nonconvex subjected constraints arising from dynamic security (height, collision, obstacle/target/threat avoidance). Finally, comprehensive solution method (CSM) presented tackle resulting problem, according its unique structures. Specifically, if all are inactive, can be simplified convex constraints, which solved by nonmonotone spectral projected gradient (NSPG) method. Oppositely, alternating direction penalty (ADPM) solve some positive constraints. ADPM introduces auxiliary vectors decouple complex separates into several subproblems tackles them alternately, while locally adjusting factor at each iteration. We show subproblem w.r.t. position vector but efficiently NSPG separable have closed-form solutions. Simulation results demonstrate that CSM outperforms unoptimized in terms performance. Besides, achieves near-optimal provided genetic algorithm much computational complexity.

Generalized Labeled Multi-Bernoulli (GLMB) densities arise in a host of multi-object system applications analogous to Gaussians single-object filtering. However, computing the GLMB filtering density requires solving NP-hard problems. To alleviate this computational bottleneck, we develop linear complexity Gibbs sampling framework for computation. Specifically, propose tempered sampler that exploits structure achieve an $\mathcal{O}(T(P+M))$ complexity, where $T$ is number iterations algorithm, $P$ and $M$ are hypothesized objects measurements. This innovation enables filter implementation be reduced from $\mathcal{O}(TP^{2}M)$ $\mathcal{O}(T(P+M+\log T)+PM)$. Moreover, proposed provides flexibility trade-offs between tracking performance load. Convergence established, numerical studies presented validate implementation.

We propose a general sensor selection (SS) methodology for ocean-of-things (OoT) where sensing network performs multiobject tracking (MOT) under resource constraints. SS methods address the combinatorial problem of determining best subset sensors that maximizes suitable reward function fixed cardinality. The novelty this article is twofold. First, we tractable information-theoretic MOT-OoT with an unknown and time-varying number objects such as ocean vessels. A essential in order to rapidly evaluate subset, which crucial high-dimensional problems encountered OoT. Second, cross-entropy (CE-SS) efficiently estimates probabilities activations determines optimal according proposed imposed cardinality constraint. CE-SS algorithm avoids exhaustive searching over space all subsets, intractable most OoT applications. methodology, coupled function, capable selecting lead more accurate than random both vessels their trajectories. demonstrate effectiveness our method via numerical simulation serveral scenarios, including multivessel emulated acoustic deployed off coast Italy.
