The invention discloses a high-frequency noise signal detection model, and the model comprises a signal time window division model which divides a signal time window; the signal time window detection model is used for dividing a signal time window into a noise signal time window and a normal signal time window; and the signal processing model is used for separating high-frequency noise signals in the noise signal time window. Multi-type noise signals in the signals are measured, classified, positioned and separated by adopting a time-space domain combined method, various noise signals can be accurately measured and separated, the loss of effective signals in the noise reduction process is reduced, and the signal-to-noise ratio of the signals is improved. 本发明公开了一种高频噪声信号检测模型，包括：信号时窗划分模型，划分信号时窗；信号时窗检测模型，将信号时窗分为噪声信号时窗、正常信号时窗；信号处理模型，用于分离出噪声信号时窗中的高频噪声信号。本发明采用时空域联合方法对信号中的多类型噪声信号分别进行测量、分类、定位、分离，能够精确测量并分离各类噪声信号，减少降噪过程中对有效信号的损失，提高信号的信噪比。
