Abstract

Abstract: A three-dimensional imaging model for ship target on sea surface is developed based on wide-band monopulse radar system and synthetic aperture radar (SAR) system. The time-varying electromagnetic (EM) scattering of ships is calculated according to the SAR geometry and the monopulse antenna model. The signal received by every antenna element is obtained, and then, the time-domain signals in the sum, azimuth and elevation difference channels are established. Through analyzing the three-dimensional image results in different grazing angles, the model validity is demonstrated.

Key words: wide-band monopulse radar, ship tatgets, synthetic aperture radar imaging, three-dimensional imaging
