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… SpletAbstract: Track-before-detect (TBD) is a popular incoherent energy integration technique aimed at improving detectability of weak targets. A number of studies are available in the literature demonstrating its efficacy against disturbance (whether noise or clutter), but most of them refer to synthetic data, i.e., relying on computer simulations. Splet13. nov. 2024 · In amplitude modulation radio-based passive radar, the track-before-detect (TBD) procedures are performed to process long time observation data.
