Aerial moving target detection is an important technology to ensure the safety of civil flight and airspace. Different from ground-based active radar space-based visible imager, on-orbit thermal infrared sensor (TIS), which records temperature difference between background targets, proved be a stable means monitoring aircraft throughout day. Limited by low spatial resolution dataset scarcity, there are few existing research based on TIS. In this paper, new multi-model joint method detect...
Although the thermal infrared remote sensing camera plays a pivotal role in Earth observation, and impacts target detection, surface temperature inversion, subsequent space missions significantly, imaging quality of is constrained by its optics, image sensors, electronics during on-orbit operation. At same time, traditional blind recovery algorithms, which require extensive time for estimating intricate blur kernels, encounter challenges due to varying atmospheric conditions other factors...
Recent rediscovered layered material-black phosphorous with a puckered honeycomb atomic structure has experienced an upsurge in demand owing to its exotic physical properties such as layer-independent direct bandgap and linear dichroism. This Letter presents plasmonic of the nanostructured BP flake unprecedented capability wide-band photon manipulation within deep subwavelength scale. Owing anisotropic characteristic band moderate mobility, strong layer number polarization dependences...
Existing infrared small target detection methods often fail due to limited exploitation of spatiotemporal information, leading missed detections and false alarms. To address these limitations, we propose a novel framework called Spatial–Temporal Fusion Detection (STFD), which synergistically integrates three original components: gradient-enhanced spatial contrast, adaptive temporal intensity accumulation, regional contrast. In the domain, introduce Temporal Regional Contrast (TRC), first...
The Sustainable Development Science Satellite (SDGSAT-1) was successfully launched on 5th November 2021. It is the world's first scientific satellite dedicated to serving United Nations 2030 Agenda for Development. To evaluate on-orbit image quality of its thermal infrared spectrometer (TIS), we propose an improved edge slope calculation method. Learning from past academic research, found that traditional slop (ES) methods are limited by various factors. For example, it demands highly...
The effective discrimination of targets from backgrounds in environments characterized by a low signal-to-clutter ratio (SCR) is paramount for the advancement infrared small target detection (IRSTD). In this work, we propose novel framework predicated on low-rank sparse decomposition (LRSD), incorporating an improved logarithmic norm and mechanism structure refinement, herein referred to as refinement (ILN-SSR). ILN-SSR more precisely characterizes properties both background target, enabling...
Thermal infrared imagery plays an important role in a variety of fields, such as surface temperature inversion and urban heat island effect analysis, but the spatial resolution has severely restricted potential for further applications. Data fusion is defined data combination using multiple sensors, fused information often better results than when sensors are used alone. Since multi-resolution analysis considered effective method image fusion, we propose MTF-GLP-TAM model to combine thermal...
The design of the thermal protection system requires high-precision and high-reliability CFD simulation for validation. To accurately predict hypersonic aerodynamic heating, an overall strategy based on mutual selection is proposed. Foremost, grid criterion wall cell Reynolds number developed. Subsequently, dependence turbulence model discretization scheme considered. It suggested that appropriate value 1 through careful comparison between one another with available experimental data....

Abstract Advances in infrared detection techniques require novel spectrum dynamic-modification strategies capable of sensing unprecedentedly low target radiant intensities. A conventional fixed-spectrum system cannot satisfy the effective stealth aircraft targets due to complex Earth background clutter and atmospheric attenuation. Therefore, a method that can highlight is urgently needed enhance detectability. In this research, set consisting different bandwidths associated with central...
Abstract In order to reflect the space-based full chain information of detection process comprehensively and objectively, we proposed a novel modular evaluation metric discuss target, background system independently. It takes equivalent radiation intensity as parameter, which can evaluate performance quantitatively. this paper, taking fifth-generation American stealth fighter F22 an example, mathematical model infrared aircraft targets in Earth is described. A proposed. The simulation...
