Stepped-Frequency Waveform radar demonstrator and its jamming

In this paper we present some applications of the stepped-frequency signal waveform designed for the obtention of HRRP (High Resolution Range Profiles) and ISAR (Inverse Synthetic Aperture Radar) images for their ulterior use in NCTI (non-cooperative target identification). For this purpose, we have developed a stepped-frequency radar demonstrator, capable of generating very stable in phase coherent pulses. A careful study thereof is presented, providing examples of actual targets as measured by the radar and discussing the main advantages and disadvantages of this waveform. On the other hand, jamming could severely affect the reliability of measurements at wartime. Consequently, we have also evaluated the impact of deception jamming on this waveform by creating a prototype jammer which can simulate both static and dynamic targets.
