摘　　要：雷达点迹模拟是雷达系统模拟的一个重要组成部分,通过雷达模拟能够有效地解决雷达在研发过程中遇到的问题,成为了雷达功能和性能测试不可或缺的手段。提出了一种基于目标运动模型的雷达点迹模拟方法,该方法包括匀速运动、匀加速运动和匀速转弯模型在内的常见的目标运动模型,同时根据中心极限定理提出了一种容易实现的高斯白噪声的生成方法。实验表明,本文提出的方法能够有效地模拟目标的运动轨迹,能够准确地模拟预定的雷达量测误差,并且该误差满足高斯白噪声的特性。Radar plot simulation is an important part of radar system simulation,which can effectively solve the problems during the development of radar,and has become an indispensable means for radar function and performance test.This paper proposes a radar plot simulation method based on target motion model which contains common target motion models such as constant velocity,constant acceleration and constant turn,and proposes a generating method of Gaussian white noise which is easy to implement according to the central-limit theorem.The experiment results show that the method presented in this paper can simulate the target motion trail effectively,can simulate the predetermined radar measurement error accurately and the error satisfies the characteristics of Gaussian white noise.
