STK EOIR - Optical Parameters Guide

Mastering EOIR Sensor Modeling in STK: Inputting Real-World Optical Parameters

Unlock the full potential of STK’s EOIR tool by learning how to accurately translate real camera specifications into high-fidelity synthetic imagery. In this course, you’ll walk step-by-step through mapping spatial, spectral, optical, and radiometric parameters from real Earth-observation cameras into STK, ensuring your simulated images and performance metrics truly reflect operational systems.

The course also highlights common pitfalls when configuring EOIR sensors in STK, such as inconsistent optical units, incorrect spectral band definitions, and mismatches between camera electronics and scene radiance models. You will learn to systematically map the main properties of real Earth-observation cameras into STK, including spatial parameters like field-of-view and detector pitch, spectral band definitions, and optical characteristics such as focal length, F-number, and system transmission. In addition, the course covers radiometric sensor parameters including detector fill factor, full well capacity, noise characteristics, and integration time. Practical examples demonstrate how each of these parameters influences synthetic image generation, signal-to-noise ratio, dynamic range, and overall image quality. By the end, students will be able to configure an EOIR sensor in STK that accurately reflects the real camera system and reliably produces mission-ready synthetic imagery for analysis.

Learning Outcomes:

From field-of-view and pixel size to wavelength bands, focal length, noise models, and full-well capacities, you’ll learn how each parameter shapes image realism. By the end, you'll be able to configure an EOIR sensor from a real datasheet and generate meaningful, mission-ready synthetic imagery inside STK.
