利用短时傅立叶变换ＳＴＦＴ（ＳｈｏｒｔＴｉｍｅＦｏｕｒｉｅｒＴｒａｎｓｆｏｒｍ，ＳＴＦＴ）的时－频域分析特性，探讨了使用各种窗口函数的ＳＴＦＴ来分析跳频信号，计算并分析了利用不同窗口函数跟踪跳频信号时所产生的各类误差（如平均误差，均方误差等）。计算机模拟结果表明，选择合适的窗口函数类型和窗口参数，利用ＳＴＦＴ进行跳频信号的跟踪、分析，可取得较好的效果。 Based on the time-frequency domain analysis of Short Time Fourier Transform (STFT), STFTs using various window functions are discussed to analyze the frequency hopping signals. The frequency hopping signals generated when different frequency hopping signals are used to track the frequency hopping signals are analyzed and analyzed. Various types of errors (such as average error, mean square error, etc.). Computer simulation results show that the selection of the appropriate window function types and window parameters, the use of STFT for frequency hopping signal tracking, analysis, can achieve better results.
