This paper shows a High-Range Resolution (HRR) Radar prototype development, transmitting in millimeter-wave
band. The waveform selected to be used is the continuous-wave linear frequency modulation (CWLFM), which allows, at the same time, good range resolution, moderate unambiguous doppler range and reasonable operational range taking into account that high-frequency band is used. The radar prototype looks for High-Range Resolution (HRR) characteristics as well as ?exibility, in order to obtain the best Inverse Synthetic Aperture Radar (ISAR) images possible depending on the applications and targets involved. That is, depending on the speed and target’s trajectories, some radar features, such as transmitted bandwidth, modulator frequency or sampling frequency, play a key role in obtaining the best possible results while using lowest electrical requirements. In Section IV, several different ISAR images are shown, pointing
out not only the radar features achieved and their variety, but also their quality thanks to the hardware and electronics improvements developed.
