Dynamic Range Definitions and Measurement Applied To Radar Digital Receiver Exciter (DREX)

Dynamic range is a performance parameter used to measure the performance of receivers. Though it has been used since the early days of radio and radar systems, there are many ways to describe and test it. The purpose of this paper is to describe five possible definitions and some of the test methods used in dynamic range characterization. The intended application is receivers used in digital receiver exciters (DREX) often found in phased array radar. The methods are described, compared, and a test example is provided. Finally, conclusions are provided with recommendations.
