Topics

Submission of research papers is encouraged. Contributions are solicited in subjects ranging from basic signature research to applications in system design, optimization and evaluation:

  • Data, techniques, models, and validation of signatures of land, sea and air targets and backgrounds, and of targets in backgrounds
  • Extension to polarization, hyperspectral and active signatures
  • Optical properties of complex surfaces
  • Models validation and metrics
  • Signature management models (infrared, spectral, passive and active)
  • Modeling and simulation of clutter (soil, maritime, atmospheric)
  • Radiative transfer, propagation models and optical data sets
  • Turbulence modeling and effects on simulation
  • Impact of climatic conditions on signatures
  • Active / Laser imaging systems

Due to the localization of the workshop, a special session will be devoted to optical signatures and related technologies in a turbulence context. All sessions of the conference will be unclassified.

 

ITBMS 2022 - Special focus on turbulence effects

Image data experiences geometric distortions and spatial-temporal varying blur due to the strong effects of random spatial and temporal variations in the optical refractive index of the photon path. Simultaneously removing these effects from an image is a challenging task.

The effects of atmospheric turbulence severely degrade image quality in the form of geometric distortions and space-time varying blur, especially in long-distance surveillance applications. Atmospheric turbulence occurs due to the turbulent flow of air cells as described by fluid dynamics and is observed throughout the extent of the atmosphere. It is particularly evident in the troposphere layer because of continuous and rapid changes of temperature and pressure near the ground surface of the earth and the air directly above it. Hence, turbulence at ground levels, known as the atmospheric boundary layer, are more severe, particularly in hot and dry environments, and their effects are more pronounced compared to that of upper layers. To address this problem, several approaches including hardware-based adaptive optics techniques and image-processing-based methods were developed to restore captured images. Due to the continuous change in the turbulence profile and the random evolution of turbulent eddies, the optical transmission path is continuously degraded.

From physical description to restoration tools... The ITBMS conference will address both theoretical and experimental approaches to start discussions with the attendees.
