false-alarm

基本解釋

The results indicate that both binomial distribution and Poisson distribution well fit the statistic characteristics of sea spike under lower false-alarm probability.
仿真分析表明，二項(xiàng)分布和泊松分布均可以在低虛警概率下較好地描述海尖峰的統(tǒng)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.
提出了一種基于周期序列的低復(fù)雜性、恒虛警幀檢測器，它的性能優(yōu)于常規(guī)的基于序列自相關(guān)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.
該方法采用傳統(tǒng)的恒虛警率（CFAR）檢測方法，但其門限設(shè)置是基于沿距離和多普勒單元功率譜值的回歸分析。

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.
