The Order Statistics Constant Alarm False Rate (OS CFAR) processing is an important method in modern radar signal processing.

有序统计恒虚警率处理(OS - CFAR)是现代雷达信号处理的一种重要方法。

The low missing rate of the coarse detection and the low false rate of the fine detection guarantee the stability of the algorithm.

粗检测的低漏判率和精检测的低误判率保证了算法的可靠性。

If one in 1, 000 people have a disease and the false-positive rate for a test is 5%, then the probability that a person testing positive has the disease is at most 2%.

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%.
