Embodiment Construction

[0041] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0042] combine Figure 1 to Figure 3 , an electromagnetic spectrum monitoring receiver signal automatic detection method, comprising the following steps:

[0043] An important reason for the low signal detection accuracy is that the difference between the signal and the strongly fluctuating background in the spectrum is not obvious, and there is a lack of effective clues to distinguish the signal from the background. In response to this problem, this patent proposes a multi-scale signal enhancement characterization method, which shows the difference between the signal and the background at different scales, and provides more and more obvious difference clue information for the subsequent discriminator through the enhanced signal characterization method. Reduce the difficulty of distinguishing between signal and spec...

Abstract

The invention discloses a signal automatic detection method of an electromagnetic spectrum monitoring receiver, which includes signal enhancement characterization and integrated learning discrimination. The signal enhancement characterization is used to obtain the local mean difference and local median difference of the spectrum of each signal under different scales and local morphological processing differences, after which an enhanced representation matrix is ​​formed. The ensemble learning discrimination includes branch detector learning and ensemble detector learning. First, the signal detection training sample set is formed by the enhanced representation matrix of multiple signals, the sample subset is allocated to train the branch detector, and the detection results are recorded; then the detection results are used to construct an ensemble Learn the training sample set and train the ensemble detector. After the training of the integrated detector is completed, the branch detector and the integrated detector are combined, and the integrated detector outputs the final automatic signal detection result. The present invention has strong signal characterization ability and signal identification ability, thereby realizing good signal detection accuracy and stability.

Description

technical field [0001] The invention relates to the field of electromagnetic spectrum monitoring receivers, in particular to a signal automatic detection method of electromagnetic spectrum monitoring receivers. Background technique [0002] In the electromagnetic spectrum monitoring task, it is necessary to detect the signal of interest from a wide range of spectrum, which provides the basis for subsequent signal analysis, demodulation, and recording operations. The traditional signal detection work is mainly done manually by the staff, which has high requirements on the operation level and signal identification level of the staff, and the detection results are easily affected by the subjective factors of the staff and are unstable. In addition, the speed of manual detection of signals is slow, which cannot meet the needs of rapid detection under dense signal conditions. Therefore, the importance of automatic signal detection functions to electromagnetic spectrum receivers ...
