摘要
在逆合成孔径雷达(ISAR)成像基本原理及信号处理过程的基础上,根据导弹的飞行弹道、自转和进动模型建立导弹飞行模型,采用自相关快速运动和累积相关运动两种补偿方法,对导弹目标的ISAR二维成像进行了仿真研究。结果表明,导弹的自旋对成像结果及积累时间的影响较大,模型不同,积累时间也不同。
Based on the general concept of inverse synthetic aperture radar (ISAR) and signal processing, the simulation of ISAR 2-D imaging for missile target under compensation methods of autocorrelation fast motion and accumulation correlation was studied according to missile flying model of flying trajectory, autorotation and precession in this paper. The results showed that the rotation of missile had a great effect on imaging and accumulation time, and the accumulation time was different for various models,
