And if it's the latter how am I to make sense of the constant alarm about USA's credit rating being raised in the news?
A state of constant alarm, emergencies, and terrorism will become a way of life, haunting Western democracies and violently destabilizing the Middle East for decades to come.
In some working-class neighborhoods--and on public transportation--the Jews of France are regularly insulted and assaulted, and "multicultural" institutions (synagogues and schools) are equally attacked: a kind of daily anti-Semitism that makes life impossible, and ultimately obliges us to live in a state of constant alarm.
So no more braking for no reason or driving unprotected because you can't stand the constant false alarms.
We focus on the issues of constant false alarm rate (CFAR) behavior, detection and false alarm probabilities.
The proposed method is compared with the CFAR (constant false alarm rate) method with a probability of false alarm P fa = 10-4 and with the energy detector proposed by Urkowitz [25], with a P fa = 10-4.
Constant false alarm rate (CFAR) detectors are designed to regulate the false alarm rate against the noise and clutter background whose mean power is unknown and (or) varying.
Controlling the FDR in a multiple hypothesis testing framework is akin to designing a constant false alarm rate (CFAR) detector in spectral target detection applications that keeps the false alarm rate at a desired level irrespective of the background interference and sensor noise statistics[22].
The Constant False Alarm Rate CFAR detector allows the radar to adjust its sensitivity while keeping the false-alarm rate reasonably constant.
From this numerical experiment, we can find that the false alarm level is comparable with different clutter covariance matrices, so the proposed detector achieves an approximate constant false alarm ratio (CFAR) with respect to different clutter covariance matrices.
