Instrumental CWLFM High-Range Resolution Radar in Millimeter Waveband for ISAR Imaging

Abstract: 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 flexibility, in order to obtain the best Inver… Show more

“…With the development of science technology, especially the highly maneuvering target and high-resolution imaging technique, there is a growing need for detection of maneuvering targets with complex motions in radar society [1]- [5]. The detection performance of moving targets affects the imaging quality, target tracking and recognition significantly [6]- [10].…”

“…3.4). It is worth noting that, despite having implemented this scheme, there are alternative configurations for signal generation such as those based on a free-running VCO, whose performance is limited by frequency sweep linearity [Bre11]; or those based on a hybrid DDS/PLL, where the DDS provides a chirp signal used as the reference input for the PLL [Coo11,Cam11]. That closed-loop configuration ensures the linearity of the frequency sweep and it is a good alternative to the selected scheme.…”
