Characterising radar cross section signature for evaluation in test range

Radar Cross Section (RCS) is one of the most important parameter that is essential for tracking as well as evaluating performance of any air-borne vehicle. There are test scenarios where there maybe multiple of such test vehicles. The test engineers face challenges in terms of discriminating the object to track and to interrogate. Therefore, RCS signature characterization is required to be done a priori. This paper focuses on characterizingRCS of air-borne vehicles and analyses the effect of radome shape in RCS signature pattern, which in turn affects the tracking performance in a test range.
