Range profiles from an experimental OFDM passive radar

Abstract

Modern communication systems provide myriad opportunities for passive radar applications. Orthogonal frequency division multiplexing (OFDM) is a popular waveform used widely in wireless communication networks today. Understanding the structure and potential of these networks becomes critical in future passive radar systems design and concept development. An experimental OFDM radar is developed and used to support ground radar imaging research using these commercial OFDM waveforms. This paper presents one-dimensional range profile results using the experimental radar setup. A brief discussion on OFDM range compression is also presented.
