摘 要: 星载雷电探测定位系统是利用光学探测器探测闪电事件的地理位置和光脉冲波形,系统采用CPLD+DSP的数字图像处理方案,利用了CPLD复杂逻辑可编程特性将系统的部分或全部功能集成在一片CPLD上,减小了系统硬件复杂程度,节省了印制版空间·利用DSP高速数字信号处理特性完成实时处理图像数据的功能·系统用CPLD完成图像信号的采集、编码和存储控制,缩小了星载设备体积,简化了电路结构;用DSP完成大量图像数据处理工作,提高了系统工作的实时性· The Lighting Detection and Orientation System is a lighting image sensor to detect the distribution and variabiligy of total lighting. A digital image processor scheme with CPLD+DSP is used in the system, because CPLD is used as a complex programmable logic device and DSP is used as the abbreviation of digit signal processor. Image signal collection, decoder and memory are controlled by CPLD, which can reduce the area of circuit board and make the structure of circuit board easier; and large member of image data in real-time can be managed with DSP because of its high speed digital processor characteristic.
