Research On ISAR Imaging Algorithm Of Missile Target

Inverse synthetic aperture radar (ISAR) is a high resolution imaging radar. It can obtain the high resolution imaging of the target with different frequency and polarization at any weather condition all the day. So, it is used in various fields such as civil economy, military and so on.Firstly, the development and the application of ISAR imaging technology are introduced. Secondly, the echo signal processing of ISAR and the STRECH method are analyzed. Thirdly, the models of a missile target are established, which include self- rotation, taper rotation and wiggle rotation. And also, the emulation of these models is presented. Finally, two methods of the correlation motion compensation and the super-resolution ISAR imaging algorithm are presented.
