摘　　要：传统的基于PC机实现的红外动态场景仿真器,实时性能差,且体积庞大,不适合外场试验。本文设计并实现了一种便携式实时红外动态场景仿真器,该仿真器以ADSP-TS201 DSP作为核心处理器,运行红外动态场景生成算法;利用FPGA实现数据输入输出,负责输出红外图像给后端信号处理设备,并接收其反馈信号;以CY7C68013A控制器扩展USB接口,作为上位主机接口,用于监控仿真器运行。文中详细介绍了该仿真器的设计与实现,并给出了实验结果。The traditional infrared dynamic scene simulator based on PC has bad real-time performance. And it is difficult to take out to experiment for its huge bulk. The simulator designed takes the advantage of embedded technology to get good real-time performance and little bulk. It uses the ADSP-TS201 as the embedded processor to run the infrared dynamic scene simulation algorithm. And the FPGA is used to solve the input and output of data, including sending the infrared image to the signal processing device and receiving the feedback signal from it. The CY7C68013A USB controller is used to extend a USB interface for the Host PC to monitor the simulator. The design and implementation of the simulator is discussed in detail. And an experiment result is provided.
