Abstract : Maintaining radar track of small targets in close proximity to much larger targets was the primary thrust of the Large Dynamic Range (LDR) program. Environmental factors and phenomenology associated with the RF tracking problem were explored to determine discriminants that could enhance the tracking performance. An RCS modeling technique was developed and verified against existing known models so the co-target interference phenomena could be simulated in a VAX computer. Six specific methods were studied and algorithms developed to determine the best method for reducing the co-target interference. An additional effect of the co-target interference phenomenology was discovered that may improve the detection process. The algorithms were employed in a tracking simulation to determine their relative performance. A future study to verify the results of the LDR program by physical measurement is recommended.
