Track before detect

In radar technology and similar fields, track-before-detect (TBD) is a concept according to which a signal is tracked before declaring it a target. In this approach, the sensor data about a tentative target are integrated over time and may yield detection in cases when signals from any particular time instance are too weak against clutter (low signal-to-noise ratio) to register a detected target. The TBD approach may be applied both for pure detection when the tentative target displays a v… Splet24. apr. 2011 · Track-before-detect 出典:『Wikipedia』 (2011/04/24 00:50 UTC 版) 英語による解説ウィキペディア英語版からの引用引用 In radar technology and similar fields, track-before-detect ( TBD) is a concept according to which a signal is tracked before declaring it a target.
