Description: This course presents the fundamentals of electro-optical (EO) & infrared (IR) sensor technology, its analysis and its application to military search, track and imaging systems. Electronic warfare (electronic attack and electronic protection) are emphasized. The course begins by studying the various classes of targets and their optical radiation characteristics including their radiant exitance and emissivity. Blackbody and graybody radiant exitance values are determined and Planck’s radiation formula is emphasized. External radiation sources are also examined including the sun, lamps and lasers. Surface reflectivity is then defined as a fraction of the irradiance at the surface that is reflected. Spectral signatures of jet nozzles and plumes are also emphasized. This is followed by examining the IR radiation transmission through the atmosphere and quantifying the optical properties of the atmosphere including the spectral, spatial and temporal radiant flux variations important in the detection and discrimination of target signatures. Rayleigh scattering and aerosol (or Mie) scattering are emphasized. Atmospheric turbulence is also treated. The effect of obscurants on the transmittance is analyzed and the effect of the extinction ratio determined. The modulation transfer function is determined as a function of spatial frequencies. The design of surface and airborne EO/IR search and track systems and their performance and analysis for several types of targets are considered as a function of the spectral, spatial and temporal discrimination techniques being used. Electronic attack against EO/IR sensors including flares, obscurations, flash and laser systems are highlighted and measures to be taken for protection are emphasized. Numerous problems will be worked through to reinforce the lecture material and the difficult concepts.
Who Should Attend: This course is intended primarily for engineers and scientists interested in the technology and design of infrared (IR) and electro-optical (EO) sensors and the electronic attack (EA) used against them. Attendees should have knowledge of the frequency spectrum and mathematics through calculus. Some probability and signal detection theory will also be helpful. Example problems are worked out to demonstrate the concepts and further the understanding of the material being presented. Some MATLAB programs are used to help students clarify difficult concepts.
