Splet09. nov. 2024 · The use of track-before-detect (TBD) of weak fluctuating targets is significant in radar systems. Conventional TBD methods may suffer from model mismatch and information waste, and the target fluctuation may not be considered. In this paper, to improve the detection and tracking performance of weak fluctuating targets using … 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…
SpletTraditional target tracking method solves ambiguities initially by performing ambiguity resolutions over thresholded measurements, while it has a poor performance when target signal-to-noise ratio (SNR) is low. Multi-frame track-before-detect (MF-TBD) is an advantageous method to track dim targets.
