Adaptive sequential algorithms for detecting targets in heavy IR clutter
Cruise missiles over land and sea cluttered background are serious threats to search and track systems. In general, these threats are stealth in both the infrared and radio frequency bands. That is, their thermal infrared signature and their radar cross section can be quite small. This paper discusses adaptive sequential detection methods which exploit ‘track-before-detect’ technology for detec...

متن کاملEfficient Nonlinear Filtering Methods for Detection of Dim Targets by Passive Systems
In this paper, we outline an efficient system for detection of dim small targets that consists of three main parts: clutter rejection, track-before-detect (TBD), and detection subsystems. Detection and tracking of dim targets requires accumulation of sensor signal in time in order to resolve the target. There exist a number of powerful methods for detecting small low observable targets with sta...
متن کاملOptimal nonlinear ltering for track-before-detect in IR image sequences
The 3D matched lter proposed by Reed et al. and its generalizations (e.g. banks of assumed velocity lters (BAVF)) provide a powerful processing technique for detecting moving low observable targets. This technique is a centerpiece of various track-before-detect (TBD) systems. However, the 3D matched lter was designed for constant velocity targets and its applicability to more complicated patter...
متن کاملNonstationary EO/IR Clutter Suppression and Dim Object Tracking
We develop and evaluate the performance of advanced algorithms which provide significantly improved capabilities for automated detection and tracking of ballistic and flying dim objects in the presence of highly structured intense clutter. Applications include ballistic missile early warning, midcourse tracking, trajectory prediction, and resident space object detection and tracking. The set of...
