舰船目标单脉冲雷达三维成像技术
THREE-DIMENSIONAL IMAGING TECHNIQUE OF SHIP TARGETS WITH MONOPULSE RADAR
-
摘要: 单脉冲雷达三维像和ISAR像相比与目标的物理尺寸相一致，在精密制导中具有重要的意义．本文分析了舰船目标三维转动引起的多普勒频移的特点，提出了在相干处理时间内利用解调频技术分离各散射点的方法．针对单脉冲测角会出现的角闪烁现象，给出了处理角闪烁的力法。仿真结果表明，本文的方法成像质量较好。

Abstract: Monopulse radar three-dimensional(3-D)images coincide with targets'size,but ISAR imaging does not hold,which is importantin 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. -
