To manage all of these uncertainties , and to optimize the probability of detection while maintaining an acceptable level of false of alarms , we are developing probabilistic models for detecting possible agents . The ultimate goal of an electro-optical imaging sensor is to achieve a high probability of detection while simultaneously maintaining an acceptably low false alarm rate . “ We are actively working to try to develop a methodology that will offer a thousand times greater probability of detection than we have now , ” said Prussin , who is a consultant on the Lawrence Livermore project . The vulnerability is increasing because of the ease of access to physical and cyber weapons and capabilities , including weapons of mass destruction ; the low cost of weapons and capabilities ; the high economic and political value of the infrastructures ; the low probability of detection given the relative anonymity of the infrastructure environments ; and the low probability of reprisal given the relative immaturity of criminal codes applicable to infrastructure disruptions . This approach incorporates both the probability a bird is available for detection and the probability of detection given availability . GBS inherently provides low probability of detection because equipment in receive-suites work without radiating signals and are relatively small . The ultimate goal of any detection system is to maximize the probability of detection while minimizing the rate of nuisance alarms . First , there is a general social advantage to creating desired expected sanctions by using low probabilities of detection in combination with high-in-magnitude sanctions , because low probabilities of detection conserve on enforcement expenditures . The four red and yellow detectable warnings ( bright red , orange-red , federal yellow , and pale yellow ) generally provided greater conspicuity and greater probability of detection than achromatic detectable warnings for a given level of luminance contrast .
