Automated Target Recognition (ATR)
We have developed a wide variety of ATR algorithms for different sensing
modalities including: Forward Looking Infra-Red (FLIR), Synthetic Aperture
Radar (SAR), airborne Laser Radar (LADAR), Ground Penetrating Radar (GPR),
video surveillance, seismic, acoustic, and others.
These have been used to detect and identify a wide variety of targets including:
tanks, automobiles, missile launchers, landmines, etc. The basic approach used
in many of these applications involves three steps: (1) non-linear image
pre-processing for noise reduction; (2) development of multiple target
detection algorithms; and (3) non-linear fusion of multi-detector outputs for
optimal detection and recognition.
An extremely robust ATR algorithm developed in our research is the Morphological
Shared Weight Neural Networks (MSNN). The MSNN is a multi-layer neural network
that combines both feature extraction (based on shape) and
classification/identification capabilities. Thus it can simultaneously be
used for both target detection and recognition.
Examples of the MSNN ATR algorithm applied to airborne LADAR, SAR, and video
surveillance imagery are shown below.
