Application of Scene Projection Technologies in the AEDC Cryo-Vacuum Space Simulation Chambers

摘要

The space simulation chambers at the Arnold Engineering Development Center (AEDC) have performed space sensor characterization, calibration, and mission simulation testing on space-based, interceptor, and air-borne sensors for more than three decades. A continual effort to implement the latest scene simulation and projection technologies into these ground-based space sensor test chambers is necessary to properly manage the development of space defense systems. This requires the integration of high-fidelity, complex, dynamic scene projection systems that can provide the simulation of the desired target temperatures and ranges. The technologies to accomplish this include multiple-band source subsystems and special spectral tailoring methods, as well as comprehensive analysis and optical properties measurements of the components involved. Implementation of such techniques in the AEDC space sensor test facilities is discussed in this paper.
