摘要
介绍了320×240非制冷红外焦平面阵列(UFPA)的信号处理系统;采用复杂可编程逻辑器件(FPGA)产生红外焦平面阵列的驱动时序,应用数字信号处理(DSP)技术实现红外焦平面阵列的非均匀校正。实验及仿真结果表明:FPGA可产生焦平面阵列所需时序,DSP对焦平面阵列的非均匀校正效果较好。
320-240 UFPA signal processing system is introduced in the paper.FPGA is adopted to generate driving time series of UFPA.The non-uniformity correction of UFPA is realized by using DSP technology.Experimental and emuiatianal resuits show that FPGA generates the required time series for focal plane arrays,and it is better to correct non-uniformity of focal plane array by using DSP.
