摘要
和差比幅单脉冲测角方法由于实现简单且测角精度高,在雷达系统中得到广泛应用。研究多输入多输出(multiple-input multiple-output,MIMO)雷达的比幅单脉冲测角技术及其精度问题,采用全微分方法详细推导了MIMO雷达和传统相控阵雷达的单脉冲测角精度,得到了准确的测角误差函数表达式。通过计算机仿真,验证了理论分析的正确性,并在相同信噪比条件下,对两种模式下的测角精度进行了比较。
The amplitude-comparison of sum and difference beams has been widely used in the radar sys-tem,as the method is easy to implement and has a high angular accuracy.The angle measuring technology and analyses of the angular accuracy are focused on.The total differential method is used to derivate the angle measure-ment precision of the method in the multiple-input multiple-output（MIMO）radar and the phased array radar,and a strict formula of the angle measurement error has been gotten,while the angle measurement accuracy of the two types of radars are compared under the same SNR conditions,and the analysis is verified by simulations.
