probability of false alarm meaning in English

虚警概率

If choosing the chaotic code with best performance and proper length , proper probability of false alarm and threshold , small acquisition time and large acquisition probability will be achieved
接收数据的最终目的是为了检测出数据,首先是对扩频信号进行解扩,其次是对剩下的载有信息的信号进行解调。
In this paper , according to the theory of signal detection and estimation , the optimal receiver pattern of pn code signal is introduced and theoretically , the relation curve of the probability of the correct detection with the input s / n ratio under the different probabilities of false alarm is illuminated
根据信号的检测和估计理论，文中分析了数字相关器实现伪码信号接收的最佳模型，从理论上计算了在不同的虚警概率下，检测概率随输入信噪比的变化曲线，并分析了doppler效应对伪码相关接收的影响。
