Automatic target recognition based on collection of evidence
The problem of automatically recognizing an object in an image scene is very difficult. This thesis develops an image-based object recognition algorithm in which information from different features is combined using Dempster-Shafer reasoning. Specific attention is paid to cases in which only …

Pose independent target recognition system using pulsed Ladar imagery
Although a number of object recognition techniques have been developed to process LADAR scanned terrain scenes, these techniques have had limited success in target discrimination in part due to low-resolution data and limits in available computation power. We present a pose-independent Automatic …

PULSED RADAR TARGET RECOGNITION BASED ON MICRO-DOPPLER SIGNATURES USING WAVELET ANALYSIS
Radar based automatic target recognition systems are commonly used in perimeter protection and surveillance applications. These systems determine the nature of a target moving in the radar's field of view using its echo signal. Such an echo signal contains the target's micro-Doppler (μ-D) signature …

Bayesian super-resolution with application to radar target recognition
… thesis is concerned with methods to facilitate automatic target recognition using images generated from a group of associated radar systems. Target recognition algorithms require access to a database of previously recorded or synthesized radar images for the targets of interest, or a database of …
