雷达目标一维距离像计算仿真研究

在雷达目标识别研究中，获取有效的雷达目标特征信号非常重要。通过计算机仿真来获取雷达目标一维距离像。仿真时先对目标外形进行三角面元逼近，利用面元法得到目标随频率变化的R苍值，进行变换后得到目标的一维距离像。给出了一类舰船目标的仿真实验。结果表明该方法在一定程度上可以较好地模拟复杂目标的雷达特征信号。最后指出了需要进一步研究的问题。

Research on radar target's one dimensional range image simulation

In radar target recognition research,it is very important to obtain effective radar target signature signal.Computer simulation was used for obtaining radar target's one dimensional range image in this paper.In simulation,the target's surface was divided into a large amount of small plate-elements,and the target's RCS varied with frequency was obtained through the plate-element method.Then these datas were transformed into target's one dimensional range image.The simulation result for a certain type ship was presented.It showed that the method can simulate well the target's complex radar signature to some extent.The problems that need further research are pointed out in the end.
