HWIL SIMULATION IN EO DOMAINOPTRO2016
Infrared camera as a weapon sub system for automatic guidance is a key component for military carrier such as missile for example. The associated Image Processing, that controls the navigation, needs to be intensively assessed. Experimentation in the real world is very expensive. This is the main reason why hydride simulation also called HardWare In the Loop (HWIL) is more and more required nowadays.
MULTISENSORS SIMULATION WITH SE-WORKBENCHOPTRO2016
Guidance of weapon systems relies on sensors to analyse targets signature. Defence weapon systems also need to detect then identify threats also using sensors. The sensors performance is very dependent on conditions e.g. time of day, atmospheric propagation, background ... Visible camera are very efficient for diurnal fine weather conditions, long wave infrared sensors for night vision, radar systems very efficient for seeing through atmosphere and/or foliage ... Besides, multi sensors systems, combining several collocated sensors with associated algorithms of fusion, provide better efficiency (typically for Enhanced Vision Systems). But this sophisticated systems are all the more difficult to conceive, assess and qualify. In that frame, multi sensors simulation is highly required.
Radar echo simulation of large scale environments including complex targetsPIERS2016
Guidance of weapon systems relies on sensors to analyze targets signature. Defense weapon systems also need to detect and then identify threats also using sensors. One important class of sensors is millimeter waves radar systems that are very efficient for all weather detection. But such sensors systems are so complex that they need simulation to be tested in a large variety of operational conditions. And the synthetic environment, which means physical target and its background (terrains, buildings, vegetation and other entities) rather than just the target itself, is very import for such sensors system simulation.
Simulating complex environments for the assessment of millimeter waves sensorsEURAD2016
Guidance of weapon systems relies on sensors to analyze targets signature. Defense weapon systems also need to detect then identify threats also using sensors. One important class of sensors are millimeter waves radar systems. However, such sensors systems are so complex that they need simulation to be tested. In this context, the SE-Workbench-RF tool is presented. The basic technical choices toward an efficient solution for radar simulation are discussed and the newly included GPU implementation is described from an accuracy and computation costs point of view. RBGM radar simulation is presented as an application example of the computation kernel.
What are the challenges of RayTracing for GNSS simulation ?InsideGNSS
The impact of the environment on the propagation of GNSS signals in constrained environments (such as urban environments) can be assessed by simulations. Indeed, simulations are relevant alternatives to test the performance of GNSS systems and services, compared to measurement campaigns in a live environment. Simulators enable users to control completely the operational parameters and then to test systems or services in different conditions. It also provides users with data to forecast the reception in a given area (for instance, for mission planning) or to analyse what happened (for instance, for mission debriefing).
