本文研究了“雷达原理”中最大信号法测角的精度问题。首先，根据最大信号法原理建立了天线接收信号模型；然后详细给出了峰值法和拟合法的测角公式；最后通过仿真研究了两种方法的测角性能，峰值法测角精度与经典文献的结论吻合，拟合法测角精度比峰值法测角精度高一个数量级。本文不仅有利于“雷达原理”研究型教学开展，而且对雷达工程实践也有参考价值。

The angle accuracy problem of maximal signal methods for radar targets is investigated. At first,the re-ceived signal model is established based on the maximal signal methods. Then,the angle formula of peak selection method and curve fitting method are presented. Lastly,the angle accuracy of the two methods is obtained by simu-lations. The angle accuracy of peak selection method is accordant with that in classical literatures. The angle accu-racy of curve fitting method is higher than that of peak selection method for one quantitative level. Both the research teaching of Radar Principles course and radar engineering practice will benefit from this work.
