The application of chaos theory to weak signal detection is a creationary research , which extends the application field of chaos theory and impels the development of weak signal detection theory 将混沌理论应用于微弱信号检测是一个开创性的研究,它拓宽了混沌理论的应用领域,将微弱信号检测理论推进了一大步。
In this paper , we introduce the intrusion detection system in the following aspects such as intrusion detection model , detection theory based on which we provide an intrusion detection system based on mobile agent 本文通过对现有的入侵检测系统的模型、检测原理进行分析研究,提出了一个基于aglet移动代理平台的入侵检测系统。
Combining the basic laws of psychophysics and signal detection theory , we use two - alternative forced - choice ( 2afc ) to study the threshold change of human electric sense under different noise levels 在心理物理实验中,结合心理物理学和信号检测论的基本原理,采用了二间隔的强迫选择法( 2afc )作为实验方法,研究不同噪声量级情况下人体电感觉阈值的变化。
The fault detection theories of local filter level and component level in the strapdown inertial navigation system ( sins ) are applied in the satellite control system . the independence and the fault tolerance ability are improved 将捷联惯导系统的元件级故障检测理论和系统级故障检测理论应用于卫星控制系统,提高了卫星控制系统的自主性和容错能力。
Detection theory, or signal detection theory, is a means to quantify the ability to discern between information-bearing patterns (called stimulus in humans, signal in machines) and random patterns that distract from the information (called noise, consisting of background stimuli and random activity of the detection machine and of the nervous system of the operator). In the field of electronics, the separation of such patterns from a disguising background is referred to as signal recovery.
