STK EOIR for Missile Defense 1:25
STK EOIR models detection, tracking and imaging performance of electro-optical and infrared sensors for:
- Space Situational Awareness
- Missile Defense
- Earth Remote Sensing
EOIR lets anyone who understands system-level sensor specifications improve their STK mission model with radiometric performance prediction. This is a unique alternative to complex, standalone sensor simulations.
EOIR was developed by Space Dynamics Laboratory (SDL), an industry leader in electro-optical and infrared sensor systems. For more than 50, years SDL has designed, fabricated, tested and deployed sensors for customers including NASA, the U.S. Air Force and the U.S. Missile Defense Agency.
New in STK EOIR 10.1:
- Motion Blur for Moving Targets or Sensors
- More Insight into Shadow Casting and Secondary Light Sources
- Improved Image Viewer – Pan and Zoom ELT Capabilities
- Capable of Simulating Twice the Number of Objects and Sensors
- More Accurate Small Target and Low Signal Modeling
Model optical and thermal properties of satellites, space debris and missiles by specifying shape, dimensions, surface material and surface temperature. Missile targets can be multi-staged with independent stage properties and solid black body plume model (temperature and emissivity).
Accurate star field
Leverage STK's database of over two million high quality star records from the Hipparcos and Tycho II catalogs to model precise position and spectral irradiance based on apparent motion, temperature and magnitude.
Include thermal and optical properties of the Earth, Moon, Sun and planets. Thermal models include diurnal, latitudinal, and seasonal variations. Optical surface properties maps are included for the Earth, Moon and Mars at 0.93 km, 2.5 km and 0.47 km resolutions respectively. The Earth includes an atmospheric model with four aersol settings.
Use just a small set of common system level specifications to fully characterize the performance of a proposed or operational sensor design. This speeds analysis and makes EOIR accessible to sensor designers and general systems engineers alike.
- Angular field of view extents
- Focal plane height and width in pixels
- Number of detection bands
- Lower and upper band edges
- Band integration time, sensitivity (NEI, NER) and dynamic range (SEI, SER)
- Effective focal length
- Entrance pupil diameter
- Diffraction wavelength
- Longitudinal defocus
- Image quality (zero, negligible, mild or moderate aberrations)
- Line of sight jitter
Report radiometric performance for point sources and extended objects through STK reports, graphs and dynamic displays. Metrics include target radiance/irradiance, background radiance/irradiance, scene photon signal-to-noise ratio (SNR), noise equivalent irradiance (NEI) and noise equivalent radiance (NER).
Sensor output images
See what the sensor would see via a dynamic sensor output image display. Improve interpretation and analysis by comparing against synchronized views in the STK 3D display and a synthetic sensor input scene window. Export sensor output images as ASCII files for use in image processing algorithms modeled in MATLAB, MathCAD or Excel.
Multi-sensor architecture analysis
Model mission architectures with up to six independently specified and steered sensors distributed across any mix of satellite, aircraft, ship or ground platforms.
