THREE-DIMENSIONAL IMAGING TECHNIQUE OF SHIP TARGETS WITH MONOPULSE RADAR
舰船目标单脉冲雷达三维成像技术

Monopulse radar three-dimensional(3-D) images coincide with targets' size, but ISAR imaging does not hold, which is important in precision guidance. The movement character of ship targets and the Doppler frequency induced by targets' 3-D rotation are analysed, and dechirping technique to separate scatterers in coherent processing interval is proposed. For angle glint induced in angle measurement by monopulse radar, a method for processing such case is achieved. Simulation results show the high quality of monopulse 3-D images.
