Synthetic aperture techniques

The use of synthetic aperture radar (SAR) techniques is becoming increasingly widespread in a number of applications ranging from satellite remote sensing of land and sea, through to target imaging from airborne radars for military purposes. The signal processing associated with high quality SAR imaging can be very complex. In addition, very large quantities of data often require to be processes and in many cases real time operation is also necessary. An introduction is provided to the fundamental principles of SAR and inverse synthetic aperture radar (ISAR), so that the requirements of suitable digital signal processors can be better understood
