摘要
针对凝视型红外预警系统在复杂海面背景下对弱小信号检测的实时性问题，提出了压缩监测区域、危险度分级、舍弃小波变换后的低频分量部分和检测图像中的零信号4种优化型算法，减少了系统的运算量，提高了系统的运算速度，满足了系统实时性的要求，并且降低了系统的虚警率，保证了系统对强起伏背景的抑制效果。
Based on the fixed IR system detecting the point target in the offing, this paper presents four kinds of optimizing algorithm to resolve the real - time problem. They are the algorithm of compressing the inspect area, the muhistep algorithm based on risk factor, the algorithm of abandoning the low frequency section after wavelet transform, and the algorithm of inspecting the signal whose amplitude is zero in the infrared imagery. These kinds of algorithm not only reduce the operation steps, enhance the speed of the system, satisfy need of the system in real - time requirement, but also reduce the false warning frequency of the system, ensure the effect that IR system restrains strong fluctuation circumstance.
