舰船目标单脉冲雷达三维成像技术

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。

THREE-DIMENSIONAL IMAGING TECHNIQUE OF SHIP TARGETS WITH MONOPULSE RADAR

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.
