SGPrime: Realistic Infrared

Scene Generation

SGPrime is a hardware-accelerated infrared scene generator designed to simulate real-world thermal environments with exceptional precision. It produces synthetic infrared imagery for use in a variety of digital and Hardware-in-the-Loop (HWIL) simulation scenarios, including:

  • In-band rendering for Long Wave Infrared (LWIR) and Mid Wave Infrared (MWIR) scenes
  • 32-bit floating point precision for highly accurate simulation
  • GPU-accelerated atmospheric effects including transmittance, path radiance, and sky temperatures
  • A comprehensive C++ API and flexible application suite with plugins and libraries
  • Real-time rendering capabilities for dynamic HWIL testing environments

MIRSAT: High-Fidelity

Seeker Simulation

A critical extension of the SGPrime platform, the Modular Infrared Seeker Analysis Tool (MIRSAT) developed for the U.S. Army Aviation and Missile Command (AvMC) that offers a GPU-accelerated simulation model of infrared seekers. MIRSAT applies real-world sensor effects to enhance realism, including:

  • Optical blur and sensor noise
  • Non-uniformity and detector imperfections
  • Seamless integration with SGPrime output for realistic digital imagery

Together, SGPrime and MIRSAT deliver a high-fidelity simulation environment that supports complex seeker analysis, algorithm development, and system validation.
