在信噪比不断变化，给出虚警概率的前提下，当给定一信噪比值后，检测概率的变化情况。-Signal-to-noise ratio changing, given the premise of the probability of false alarm, when given a signal-to-noise ratio values, the probability of detection of changes.

给定一特定信噪比，检测单节点在这一信噪比的虚警概率随检测概率的变化仿真曲线图。-Given a specific signal-to-noise ratio, the detection of a single node in the signal-to-noise ratio of the probability of false alarm detection probability changes with the simulation graph.
