Abstract:

This report is an investigation of the effects of anomalous propagation of radar waves, caused by subrefractive layers and elevated ducts, on aircraft radar performance and possible tactics. A test and evaluation of radar coverage for various environmental scenarios is conducted using the Integrated Refractive Effects Prediction System IREPS model. From the results of each scenario, a decision matrix is created and applied as an analysis tool for determining satisfactory flight profiles for a given mission. The findings are discussed for both a radiating and non-radiating aircraft perspective. Environmental data collected from the Mediterranean Sea and Northern Arabian Sea were analyzed and used to determine the test scenarios. Keywords include anomalous propagation, subrefractive layers, and ducting.
