摘要
本文针对线性调频信号的时域加权问题，做了大量的计算机模拟，并对各类数据加以汇总和分析。在分析典型窗函数的基础上，笔者提出了一种适合于线性调频信号加权的新型窗函数──梯形窗函数。
A lot is done in this paper on linear FM signal time weighting through simulta- tions on the computer. By analysing typical window functions, the auther finds out a new window function──Trapezium window function, which fits linear FM signal time weight- ing.
