False alarm detection
The term “false alarm” refers to alarm systems in many different applications being triggered by something other than the expected trigger-event. Examples of this those applications include residential burglar alarms, smoke detectors, industrial alarms, and signal detection theory. The term “false alarm” may actually be semantically incorrect in some uses. For example, a residential burglar alarm could easily be triggered by the residents of a home accidentally. The alarm is no… Webfalse alarm definition: 1. an occasion when people wrongly believe that something dangerous or unpleasant is happening or…. Learn more.

Web(ISOS) is to balance miss detection (MD) and false alarm (FA). This usually needs “opposite” strategies to suppress the two terms and has not been well resolved in the litera-ture. In this paper, we propose a deep adversarial learning framework to improve this situation. Departing from the tradition of relying on a single objective to ... WebThe described method for reducing “ghost cell” false alarms may allow the detection of a real cell sharing those cyclic shifts since the method regularly subtracts the signature of every detected cell while keeping the contributions from other cells. In an example, the maximal value in every one of the 2 * N seq pre-calculated signatures ...

WebApr 11, 2024 · The objective of this research is to find the probability of detection of fluctuating targets. The plot between detection probability, false alarm probability, and signal-to-noise ratio (SNR) will be made for Swerling fluctuating target models. The variation of the scattered signal is based on radar cross section (RCS).
