摘　　要：针对红外焦平面阵列(IRFPA)非均匀性校正过程中运算量大,难于实时实现的特点,提出利用DSP实现红外焦平面阵列非均匀性实时校正方法。在介绍多点校正原理的基础上,详细阐述了DSP硬件实现多点校正的过程及其关键技术,并给出了实验结果。实验表明该硬件校正方法简单灵活,图像效果理想,能够有效地解决红外焦平面阵列非均匀性实时校正难题。A hardware correction system based on DSP has been proposed because of large amounts of data calculation during the course of infrared focal plane array（IRFPA） nonuniformity correction and difficulty in real-time realization. The DSP hardware correction process and its key techniques are explained in detail on the basis of introducing the correction principle for many points. At last, the experimental results are given. The experiment shows that the correction method is simple and flexible, and imaging quality is satisfactory, and the nonuniformity realtime correction problems of IRFPA may be effectively solved.
