摘要
由于海浪的影响造成海上舰船运动形式复杂多变,因此要获取高质量舰船目标逆合成孔径雷达(ISAR)的图像非常困难。本文对基本的舰船目标运动模式下ISAR成像问题展开研究。首先分析舰船目标的转动模式,建立3种基本的转动形式的数学模型。研究距离-多普勒(R-D)算法在该运动形式下的ISAR成像。通过仿真实验证明R-D算法可以获取较高质量的小幅度舰船转动ISAR图像。
Maritime ship motion model is very complicated due to the influence of the waves offshore,it cause getting high quality ship target image by inverse synthetic aperture radar( ISAR) technology is a very difficult task. This paper launches the research on ISAR imaging under the condition of the ship motion. Firstly,we establish the mathematical model of the three basic rotation forms through the analysis of the rotation motion of ship targets. Then,we studied the Range-Doppler algorithm in the application of ship target ISAR imaging under the rotation motion. Finally,the simulation experiments prove that Range-Doppler algorithm can get high quality of the slight ship rotation ISAR image.
