Abstract:

In this work, a generalized ISAR approach to solve the SAR problem for image reconstruction and ship target recognition is suggested. A new coordinate definition of the 3D SAR scenario is addressed. An analytical geometrical approach to define apparent Yaw, Pitch and Roll angle of the ship target at sea is implemented. Mathematical expressions to determine slant range distance are derived. The model of the SAR signal return is composed by a linear frequency modulated transmitted signal, geometry and reflectivity properties of sparkling points of the object. Image reconstruction procedure includes correlation range compression and fast Fourier transform azimuth compression. To verify the new ISAR image reconstruction concept with respect to SAR problem a numerical experiment is carried out.
