在明确虚警率和探测率概念基础上,建立了虚警率和探测率与信噪比之间相互关系的定量模型,通过模拟计算给出信噪比对虚警率和探测率的影响.计算结果表明:要使虚警率控制在10%以内,信噪比应该达到5.0以上;要使探测率达到90%,信噪比应该达到5.2～5.7.

Based on the clear define of lightning dectection efficiency and false alarm rate,and quantitative models is built to illuminate the influence of signal-to-noise ratio on LDE and FAR. Simulating calculation results show that to control FAR below 10%,the signal-to-noise ratio should be as big as 5.0 at least;and to keep LDE 90%,the signal-to-noise ratio should be between 5.2 to 5.7.
