全向红外搜索跟踪系统的设计与实现

针对传统红外探测系统视场小、扫描速率低的缺点，设计了一种快速全向红外搜索跟踪系统，通过反射镜面在俯仰和方位上的高速旋转，实现了整个球面空域在红外探测器上的快速成像。利用高性能ADSP-TS201处理器，完成了高速扫描图像的实时处理系统设计，并重点分析了系统设计中的关键技术问题及解决途径，以及实现核心处理模块的方法。实验结果表明，该系统可以完成快速搜索、全向扫描以及对图像的实时处理。

System design and realization of the all-direction IRST

Traditional infrared detection system has small viewing field and low scanning speed, an all- directional IRST system with high scanning speed is designed, which quickly images the whole spherical airspace on the infrared sensors by the reflector circumrotating in pitching and azimuth with high speed. The real-time processing system for high-speed input images is constructed based on the processor ADSP-TS201 with high performance. The key problems and their solutions are analyzed emphatically as well as the realization ways of some core modules. The experimental result indicates that the all-directional IRST system has the function of quick search, all-directional scan and real-time processing image.
