“…Software for the simulation of spectral light reflections from spacecraft has been presented in multiple publications so far. Probably the most frequently referenced of these is the Time-domain Analysis Simulation for Advanced Tracking (TASAT) [11] created by the U.S. Air Force Phillips Laboratory. Further approaches that can be found in published literature include the Digital Imaging and Remote Sensing Image Generation (DIRSIG) suite [12] of the DGIRS Laboratory at Rochester Institute of Technology and the CanCurve software [13] introduced by Willison and Bédard.…”

Spectral Light Curve Simulation for Parameter Estimation from Space Debris

Characterisation of space debris has become a fundamental task to facilitate sustainable space operations. Ground-based surveillance provides the means to extract key attributes from spacecraft. However, signal inversion attempts are generally under-constrained, which is why an increase in measurement channels through multispectral observations is expected to benefit parameter estimation. The current approach to simulating space debris observation at the Institute of Technical Physics of the German Aerospace Centre (DLR) in Stuttgart relies on monochromatic images taken from the POV-Ray render engine to form light curve signals. Rendered scenes are generated based on the location of an observer by propagating a target’s orbit and rotation. This paper describes the simulation of spectral light curves through the extension of DLR’s Raxus Prime simulation environment. Light reflections are computed using the Mitsuba2 spectral render engine, while atmospheric attenuation is accounted for by the radiative transfer library libRadTran. A validation of the simulator was achieved using multispectral measurements, carried out at the Uhlandshöhe research observatory in Stuttgart. Measured and synthetic data were found to be in agreement based on an RMS error <1% of the total measured signal count. Further, simulated spectral products were used to determine a target’s surface material composition and rotation state and examine aspects of laser ranging to non-cooperative targets.

“…The space situational 3D scenario member. (6) The main function of the space situational scene member is to display space situational 3D scene and 2D scene of the moving space-based platform and target in real time during the simulation running. It also can show the scene in the field of view of the laser active imaging system, and the coverage situation of the target.…”

“…Air Force Research Laboratory has developed TASAT to evaluate the electro-optical detection system performance and optimize system design accurately. It can simulate and analyze the active or passive tracking and imaging process of the satellite, missile and other targets [6] . Boeing has developed SVST, which can simulate satellite or missile optical ray-traced signatures, and render target images under the condition of active laser illumination and solar passive illumination.…”

This paper adopts the High Level Architecture to develop the space-based laser active imaging distribution simulation software system, and designs the system framework which contains three-step workflow including modeling, experimental and analysis. The paper puts forward the general needs of the simulation system first, then builds the simulation system architecture based on HLA and constructs 7 simulation federal members. The simulation system has the primary functions of space target scattering characteristic analysis, imaging simulation, image processing and target recognition, and system performance analysis and so on, and can support the whole simulation process. The results show that the distribution simulation system can meet the technical requirements of the space-based laser imaging simulation.

“…In this model, the track error due to speckle is computed as follows: Strictly speaking, the tracking performance should depend on the power spectrum of the speckle disturbance, but high-fidelity simulations of the effect using TASAT (ref. 15) suggest the spectrum is white over a broad range of temporal frequencies.…”

Active tracking lasers for precision target stabilization

Lasers have historically been considered in the context of weapons, but recent progress has also permitted us to consider using lasers for more subtle applications such as designation, tracking, and discrimination. In this paper, we will review the state of the art of active tracking, including effects such as laser beam quality, diffraction, atmospheric turbulence, and other aspects of laser interactions with the propagation environment. We will present the theory for using lasers in relatively low-power tracking applications.
