Design and Implementation of Multistage Infrared Early Warning System
摘要
Abstract
For infrared warning system analysing suspicious incoming targets, to reduce the contradiction between the less response time and the lower false alarm rate, it is proposed a multistage warning mechanism of infrared early warning and real-time image processing system design scheme, which sets the alarm level according to different detection and treatment results of different levels of the alarm signal given. For the push-broom type infrared imaging characteristics of early warning system, multi-channel processing method is adopted to enhance the system real-time performance. To meet the needs of multi-level warning and multi-channel processing method, hardware is multi-core architecture based on Xilinx company's Virtex 5 FPGA and TI company DSP TMS320C6455 as the core processor, which develops the DSP arithmetic kernel within the FPGA , enhancing the capacity of the system. Experiments show that the multistage infrared warning and multi-channel processing technology can satisfy the requirement of false alarm rate while improving the system efficiency.关键词
