Sensor xpert sensor simulation platform  


VRAD sensorxpert Sensor simulation platform is a set of sensor simulation platform based on thermal physical calculation and engineering test data, considering atmospheric transmission characteristics and complex background environment. It can generate real-time dynamic high-resolution images (including visible light, night vision, infrared, SAR, etc.) of target and environment scene, which is widely used in multi band imaging simulation.

The sensor simulation platform has high-precision terrain model library and target model library, which can be customized and developed according to the actual engineering requirements of users. The sensor simulation platform provides a semi-automatic material division tool to effectively reduce the difficulty of material processing. It has built-in 300 + verified material files, and users can modify the material library parameters or create custom materials. The sensor simulation platform provides real-time and accurate atmospheric radiation transmission model through highly optimized MODTRAN source code. The sensor simulation platform has unparalleled advantages in the secondary development capability. By setting the output channel number, channel arrangement and other parameters, the sensor simulation platform can meet customers' requirements for output display. In addition, the sensor simulation platform provides rich physical interfaces to meet the requirements of various hardware in the loop and injection simulation.
