摘　　要：矩阵式太阳敏感器系统是精度高、测量信息量大并能快速处理的敏感系统。文章设计的矩阵式太阳敏感器,利用光敏电阻作为敏感元件,将光敏电阻排列成4×4矩阵,采用狭缝式光学头部,同时采集到两个轴姿态夹角的数字信息;利用ADC0809对光敏电阻的信号进行模数转换,由单片机STC89C52实现数据的采集和处理,将结果在LCD液晶显示器显示,同时通过串口将结果传输到上位机。实验结果表明,该太阳敏感器具有一定的精度,在一定范围内能够满足太阳的角度测量。Matrix type sun sensor system is a sensitive system with high precision, high measurement information and fast processing. In this paper, the designed matrix sun sensor using photo-resistors as the sensitive element,, the photo-resistors are arranged in a 4 ~ 4 matrix, the slit type optical head is used to acquire the digital information of two-axis attitude angle; The ADC0809 converts the analog signals to digital signals; The microcontroller unit （MCU） STC89C52 is used to process the signal and output the sensing results tO LCD unit. Meanwhile, the results are transferred to the PC by serial port. The experimental results show that the sun sensor has a certain precision, can meet the sun＇s angle measurement in a certain range.
