摘　　要：介绍一种基于高速信号处理器TMS3 2 0C3 1的战术导弹天线罩瞄准线误差补偿系统。它采集导引头俯仰和偏航两伺服通道的角反馈电位计和多普勒频率信号及输出俯仰和偏航两指令通道的补偿信号。系统输入数据经A/D定时采集进入数据缓存器 ,CPU采用读存储器的方式读进数据 ,经过运算后D/A输出并与导引头指令相加送给自动驾驶仪。利用射频仿真系统对该补偿系统进行动态实物联试 ,试验表明该补偿系统达到了很高的补偿精度。In this paper, a compensating device of sight line error based on DSP for missile radome is introduced. Its inputs are composed of feedback signals of pitch and yaw angles and Douplar frequency, whose outputs are signals compensating for the seeker command outputs. The input data is gathered into data buffers by A/D. CPU reads the data from the buffers. The D/A outputs of DSP added with the seeker command outputs are given to the autopilot. The test for compensating of the sight line error for missile radome has been done by the semi-real simulation system, which shows the highly precise compensation for missile homing.
