| Abstract: | Millimeter wave radar is featured by high resolution, miniaturization and lightweight. It is an important development direction of modern radar applications. With the breakthrough of W-band components, the research of W-band inverse synthetic aperture radar (ISAR) system has been a hot spot. W-band ISAR images have high resolution and rich scattering details, which can improve the accuracy of target classification and recognition. Thus, it has great application value in military and civilian fields. This paper introduces a W-band frequency modulated continuous wave (FMCW) radar system operating at 94 GHz and with a bandwidth of 5 GHz. The performance of this system is discussed for ISAR applications, and FMCW mode ISAR imaging procedures are introduced. The ISAR turntable test is carried out by using the system, and the preliminary imaging results of the ISAR system are obtained by using the RD algorithm. |
