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.
仿真分析表明，二项分布和泊松分布均可以在低虚警概率下较好地描述海尖峰的统计特性。
A low-complexity CFAR (const false-alarm rate) frame detector is proposed, which exploits periodic structure of preamble and outperforms conventional autocorrelation detector.
提出了一种基于周期序列的低复杂性、恒虚警帧检测器，它的性能优于常规的基于序列自相关检测器；
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.
该方法采用传统的恒虚警率（CFAR）检测方法，但其门限设置是基于沿距离和多普勒单元功率谱值的回归分析。

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.

虚警
After the preprocessing, the Constant-False-Alarm Rate (CFAR) technique is used to detect the moving targets at a constant false-alarm rate.
预处理之后,再利用恒虚警(CFAR)技术完成在恒定虚警率条件下对运动目标的检测。
