摘要: 在红外信号处理中,红外探测器原始输出图像存在非均匀性严重、噪声大、对比度低等问题,无法满足武器装备对图像质量的要求。为解决红外图像信号数据量大、算法复杂、系统实时性强等系列问题,研制红外探测器集成图像信号处理电路,以减小体积、降低功耗、提升性能。Abstract: In infrared signal processing, the original output image of the infrared detector has serious non-uniformity, high noise, and low contrast, which cannot meet the requirements of the image quality of ammunition. To solve problems such as large amounts of infrared image signal data, complex algorithm, and strong real-time performance of the system, the integrated infrared signal processing circuit is developed for reducing the volume and improving performance.
