false-alarm

基本解释

The results indicate that both binomial distribution and Poisson distribution well fit the statistic characteristics of sea spike under lower false-alarm probability.
倣真分析表明，二項分佈和泊松分佈均可以在低虛警概率下較好地描述海尖峰的統計特性。
A low-complexity CFAR (const false-alarm rate) frame detector is proposed, which exploits periodic structure of preamble and outperforms conventional autocorrelation detector.
提出了一種基於周期序列的低複襍性、恒虛警幀檢測器，它的性能優於常槼的基於序列自相關檢測器；
It uses a conventional constant false-alarm-rate(CFAR) detection procedure but the thresholding scheme is based on regression analysis of power spectrum values along range and Doppler cells.
該方法採用傳統的恒虛警率（CFAR）檢測方法，但其門限設置是基於沿距離和多普勒單元功率譜值的廻歸分析。

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%.
FORBES: A Nose For Bombs
CT2WS succeeded in creating a technology kit capable not only of identifying up to 91 percent of targets during testing with extremely low false-alarm rates, but also widening a warfighter's field of view to 120 degrees when all components of the kit are used in tandem.
ENGADGET: DARPA threat detection technology uses a camera to see targets, software and soldier brains to identify them
Although the rumors that Obama - whose father and step-father were Muslims and who was educated in Muslim schools in Indonesia - is a Muslim are demonstrably false, his Christian affiliations are a cause for alarm in and of themselves.
CENTERFORSECURITYPOLICY: The audacity of truth

When you think something dangerous is about to happen, but then discover that you were mistaken, you can say that it was a false alarm.

虛警
After the preprocessing, the Constant-False-Alarm Rate (CFAR) technique is used to detect the moving targets at a constant false-alarm rate.
預処理之後,再利用恒虛警(CFAR)技術完成在恒定虛警率條件下對運動目標的檢測。
