In the field of radar, nonlinearity has always been significant challenge in target tracking algorithms. It is evident complexity motion model, observation and maneuverability target. Traditional model-based algorithms often rely on numerical approximations or simulations to obtain suboptimal solutions, which may lead conversion errors increase algorithm complexity. Model-free methods based deep neural networks have continuously employed nonlinear (NTT) improve state estimation performance....

Front Cover: In article 1800362, Lu Shen, Peng Chen, Guangyuan Zhou and co-workers present different degrees of ethylene-confined polymerization in porous polymer microspheres with an interconnected tri-modal pore structure.

With the increasing penetration of distributed photovoltaics (PVs) in active distribution networks (ADNs), risk voltage violations caused by PV uncertainties is significantly exacerbated. Since conventional regulation strategy limited its discrete devices and delay, ADN operators allow PVs to participate optimization controlling their power outputs cooperating with traditional devices. This paper proposes a decoupling rolling multi-period reactive considering strong time coupling between...

While it also reduces efficiency test, increases test cycle. This paper presents a new scheme by an automatically generated method. Through description, we establish automatic generation system about scheme, for network analysis model (AGPTSAM) is established, then termination AGPTSAM proved pushdown automaton. prototype implemented. could provide...

Abstract:<div><br><div><pre><p>In system identification scenarios, classical adaptive filters, such as the recursive least squares (RLS) algorithm, predict impulse response. If a tracking delay is acceptable, interpolating estimators capable of providing more accurate estimates time-varying responses can be used; channel estimation in communications an example applications.

The performance of traditional model-based constant false-alarm ratio (CFAR) detection algorithms can suffer in complex environments, particularly scenarios involving multiple targets (MT) and clutter edges (CE) due to an imprecise estimation background noise power level. Furthermore, the fixed threshold mechanism that is commonly used single-input single-output neural network result degradation changes scene. To overcome these challenges limitations, this paper proposes a novel approach,...

This paper addresses the localization of a target in 3D scenarios using bistatic range measurements with single passive receiver and multiple transmitters. The main-lobe beamwidth receiving antenna contains valuable <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">a-priori</i> information about position but is commonly overlooked. study introduces an angular constraint to incorporate into elliptic localization, resulting Quadratically...

For underwater acoustic (UWA) communication in sensor networks, the sensing information can only be interpreted meaningfully when location of node is known. However, localization a challenging problem. Global Navigation Satellite Systems (GNSS) used terrestrial applications do not work underwater. In this paper, we propose and investigate techniques based on matched field processing for single-antenna UWA receiver relative to one or more transmit antennas. Firstly, demonstrate that...
