Monopulse Radar 3-D Imaging and Its Application in Terminal Guidance Radar

单脉冲三维成像综合利用了ISAR、单脉冲测角和三维成像处理技术而得到能够真正反映目标实际尺寸的三维像,即利用方位差波束、仰角差波束和径向距离三个测量参数中的任意两个而构成三维物体的三视图。本文简单介绍了单脉冲雷达三维成像的基本原理,研究了目标姿态变化对三维成像的影响及其基于(μ-f_d)图的三维运动补偿方法,展望了其在末制导雷达中的应用。计算机仿真结果表明:单脉冲三维成像在对目标与舷外干扰识别和对目标要害部位实施精确攻击等方面具有明显的优越性,在末制导雷达中具有重要的应用价值。

Monopulse radar 3-D imaging integrates ISAR. monopulse angle measurement and 3-D ima-ging processing to make 3-D image which can reflect the real size of a target, which means any two of thethree measurement parameters, namely azimuth error beam. elevation error beam and radial distance. canbe used to form 3-D image of 3-D object. The basic principles of monopulse radar 3-D imaging are intro-duced,the effect of target carriage change on 3-D imaging and the 3-D moving compensation based on the (μ-f_d) figure are analyzed. and the application of monopulse radar 3-D imaging to terminal guidance radars isforecasted. The computer simulation results show that the monopulse radar 3-D imaging has apparent ad-vantages in distinguishing a target from overside disturbances and precisely assaulting on vital part of a tar-get,and has great importance in terminal guidance radar.
