Embodiment Construction

[0027] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] In essence, the recognition problem of radar signal waveform modulation mode is the problem of pattern recognition and classification. Before identifying and classifying radar signal waveform modulation methods, it is necessary to extract numerical features from radar signals, and then identify and classify numerical features. Based on this situation, a recognition method is proposed by analyzing the time-domain features and frequency-domain features of radar signals through image analysis. Through the time-domain characteristic map and the frequency-domain characteristic map, the traditional numerical analysis mode of characteristic parameters is skipped, and the method can intuitively identify the modulation mode of the radar signal waveform.

[0029] The invention processes the data of the radar signal, and firstly extracts three ch...

Abstract

The invention discloses an image-based radar signal waveform modulation mode identification method and platform and a medium. The method comprises the steps: S1, establishing a modulation mode to identify an original data image library; S2, reducing an identification data volume to highlight a radar signal contour; S3, obtaining a time domain graph and a frequency domain graph of a radar signal to be identified; S4, comparing the time domain graph of the radar signal to be identified; S5, comparing the frequency domain graph of the radar signal to be identified; and S6, determining the modulation mode of the radar signal to be identified. According to the method, direct analysis of a large number of numerical values is omitted, special image processing is used for the characteristics of a radar modulation mode, and the recognition accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of radar. Specifically, it relates to an image-based identification method, platform and medium of radar signal waveform modulation mode. Background technique [0002] In modern warfare, electronic warfare is particularly important, and radar is an essential reconnaissance device in electronic warfare. Radar is an important tool for detecting target information. By analyzing the received radiation source signal, the purpose of detecting radiation source related information is achieved. As an extremely important means of electronic reconnaissance, radar is the key to the radar reconnaissance mission when it detects the target radar emitter signal, and its analysis and identification. Only by accurately identifying the target emitter signal can an effective analysis be made. At present, the identification of radar signal radiation sources is generally judged by the value of characteristic parameters. Tradit...
