The influence of finite range cells on false alarm performance is also analyzed and the modified threshold coefficients are given.

分析了有限的参考单元数对虚警性能的影响，并给出了修正的门限系数。

Correct rate is increased further, while, false alarm rate is decreased effectively. Also, performance of the new system is more stable and reliable.

新系统的正确率得到进一步提升的同时，虚警率得以有效降低，并且，具有更为稳定、可靠的性能。

For any PN code acquisition system in spread spectrum communications, the acquisition performance is largely dependent on the probabilities of detection and false alarm.

对于任何一种扩频通信p N码捕获系统来说，捕获性能在很大程度上取决于检测概率和虚警概率。

Fido can pick up the smell of TNTvapor at concentrations of just a few parts per trillion, and it was the first sensor to find buried mines at a level comparable to dog performance, with a false-alarm rate of less than 5%.
