Complementary code ISAR technique for stealth target detection and identification

In this paper an original ISAR technique for stealth target detection and image reconstruction is analyzed. Geometry of 2-D ISAR scenario and analytical expressions for trajectory target determination are suggested. A model of the complementary phase code ISAR signal reflected by environment in the presence of the stealth target is created. Autofocusing procedure using first point with the lower intensity is applied. Correlation range compression and FFT azimuth compression image reconstruction is performed. To verify the correctness of the model and ability of the ISAR technique for stealth target detection and image reconstruction numerical experiment is accomplished.
