Automatic Target Recognition from ISAR Images: A Review

Inverse Synthetic Aperture Radar (ISAR) is one of the promising imaging radar technology used in military applications mostly. ISAR picture productions are extremely good at predicting common radar targets such as aircraft, missiles, military vehicles, battleships, and space objects. Even though extensive research work is going on the classification/recognition of targets from ISAR imagery, no study has been performed to compile and compare those works. This paper presents a review of research works done on Automatic Target Recognition/Classification (ATR/ATC) from ISAR imagery. This work will be helpful for the researchers to have a comprehensive overview of the research progress.
