Abstract

The evolutionary design, signal conditioning, performance prediction and validation with experimental data of robust centralized fusion algorithms (CFAs) that operate in clutter, with unspecified distribution, are presented. Two CFAs, called non-coherent integration and T-squared, followed by an adaptive constant false alarm post-processing along with several variants were evaluated. The fusion algorithms were designed to provide various degrees of robustness and inherent CFAR properties to Weibull and Lognormal clutter. Each algorithm's fusion performance, defined via receiver operating characteristics (ROCs), was compared and also compared to the ROCs of the individual sensors (both by Monte Carlo simulation and by the use of measured data with target in clutter). The test results with both target in the clear and target in clutter data are in concert with the theoretically predicted behavior.
