| 摘 要： | 由于ESPRIT算法结构封闭,不需要搜索过程;而且输入数据阵经过简单的矩阵变换,可以由复数域变换到实数域,利用变换后的实数数据阵的特殊结构,引入基于实数运算的特征值求解过程,其运算复杂度明显减小;再者,ESPRIT算法结构本身便于并行处理等.依据这些特点,基于ESPRIT算法,给出了一种适用于雷达的快速测频算法.仿真结果显示算法测频精度高,运算复杂度小,适用于雷达快速测频.

| Abstract: | ESPRIT algorithm is form-closed without search procedure, and the input data matrix can be changed into real from complex through simple matrix transformation. Utilizing the special structure of the data matrix that has been transformed, based on real eignvalue solution procedure, the computation complexity gets smaller considerably. What is more, the structure of the ESPRIT itself is fit for parallel processing. According to the characteristics mentioned above, this paper presents a fast algorithm for the sake of measurement of frequency of return signal in radar based on the ESPRIT, which is of higher precision and lower computation complexity, and is applicable to radar signal processing according to simulations. |
