STK在航电传感器设备试验环境中的仿真应用

随着航空电子传感器设备研制领域的不断发展,设备的试验已不再局限于单一设备的功能,而是需要在复杂的自然和电磁环境中将所有设备集成起来进行系统级试验。依赖传感器设备载机在真实环境的不断试飞,这不仅试验成本高,且设备故障的定位和复现也相当困难。针对这一系列的问题,利用STK软件能建立复杂的陆、海、空、天仿真应用场景,并能提供易于理解的图表、文本、可视化分析报告的特性,实现载机航迹数据生成、传感器以及天线仿真应用分析、地理数据加载、地形遮挡分析、复杂电磁仿真环境分析、真实机载数据回放以及可视化演示等功能。该应用为实装机载航电传感器设备研制提供最佳的系统级试验仿真环境,实现试验研制过程的降本增效。

SIMULATION APPLICATION IN AVIONICS SENOR EQUIPMENT TEST ENVIRONMENT BASED ON STK

With the continuous development of the field of avionics sensor equipment,the test of the device can no longer be limited to a single device function.It requires integration of all devices in a complex natural and electromagnetic environment for system-level testing.Relying on aircraft which carries sensor device to do continual flight in real environment not only causes high testing cost,but also is quite difficult to locate the equipment failures and do recurrence.To solve this series of problems,STK was adopted to establish complex simulation application scenarios on the land,in the sea,in the air and in space.It could provide the comprehensible characteristics of graph,text and visualization analytical reports.STK could implement the functions of flight path data generation,sensor and antenna simulation application analysis,geographic data loading,terrain occlusion analysis,complex electromagnetic simulation environment analysis,real airborne data playback and visual demonstration.It provides optimal system-level testing simulation environment for real avionics sensor equipment development,decreases cost and improves efficiency in the developing process.
