Inverse synthetic aperture 3-D imaging laser radar

Three-dimensional (3-D) Image can represent target´s physical characteristic well and improve target recognition capability, however, conventional optical imaging radar which is limited by the array units or scan system cannot realize the high resolution imaging for moving targets. This paper combines the inverse synthetic aperture technology, laser signal and interferometric technique to suggest a new radar system which is called Inverse Synthetic Aperture 3-D Imaging Laser Radar, describes initial design project of this radar system, analyzes the imaging theory and implement method, and finishes the imaging simulation. The simulation shows the feasibility of this radar system and advantages of the image obtained from this radar.
