Evaluation of a Correlation-Sensitive Automatic Clutter Eliminator.
Abstract
A prior computer simulation conducted by MITRE Corporation indicated that an automatic clutter eliminator (ACE) using correlation information within the clutter sum register of the common digitizer (CD) could be used to improve target detection and reduce false targets due to radar weather clutter. Project personnel at the National Aviation Facilities Experimental Center (NAFEC) designed and fabricated a real time hardware device to perform the correlation estimation and lead edge generation according to the MITRE requirement. A series of tests was conducted to compile data comparing digitizer performance using the correlation-sensitive ACE/CD with performance from an unmodified CD. Test results indicate reductions in false targets up to 30 percent are possible with no loss of real target detection. It was concluded that further field testing of correlated ACE techniques be accomplished to confirm performance under many various radar and weather situations. (Author)
