Target 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.
Celestial bodies
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.
Sensor specification
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 STK/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
Sensor performance
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 3-D 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.
