An overview of high range resolution radar techniques

Abstract

The various ways that high range resolution operation can be achieved in a radar system are reviewed. Both simple pulse and pulse compression techniques are discussed. For the simple approach, monocycle radar, a form of ultra-wideband radar, is emphasized. For the pulse compression approach, both phase and frequency coding of the carrier is considered. for phase coding, the multiplicity of codes and sidelobe suppression filtering techniques are emphasized. For frequency coding, the emphasis is placed on correlational compression, nonlinear frequency modulation, and stepped frequency approaches. Performance analyses are presented, and the strengths and potential drawbacks of each technique are discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
