Robust detection theory can be come back to the paper published by fluber in 1965 , it has been developed quickly and has many practical applications in various fields for its robustness against deviation from assumed models and against error as well as other robust signal processing methods Robust检测理论最早于1965年由huber提出,由于它具有抗干扰和抗误差能力,因此在实际应用中发展较快,并且robust处理技术在各个领域内也都得到重视和发展。
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.
