Embodiment Construction

[0026] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] In essence, the recognition problem of radar signal waveform modulation mode is the problem of pattern recognition and classification. Before identifying and classifying the radar signal waveform modulation mode, it is necessary to extract numerical features from the radar signal, and then identify and classify the numerical features. Based on this situation, this paper proposes a method to identify the radar signal by analyzing the time-domain and frequency-domain features of the image. Through the time-domain feature map and the frequency-domain feature map, the traditional numerical analysis mode of characteristic parameters is skipped, and this method can intuitively identify the modulation mode of the radar signal waveform.

[0028] The present invention processes the data of the radar signal, and firstly extracts three features...

Abstract

The invention discloses an image-based radar signal waveform modulation mode identification method, platform and medium. The method of the present invention includes the step S1 of establishing a modulation method to identify the original data image database, the step S2 of reducing the amount of identification data and highlighting the outline of the radar signal, the step S3 of obtaining the time domain diagram and the frequency domain diagram of the radar signal to be identified, and comparing the radar signal to be identified. The step S4 of the time domain diagram of the signal is compared with the step S5 of the frequency domain diagram of the radar signal to be identified and the step S6 of determining the modulation mode of the radar signal to be identified. The invention skips the direct analysis of a large number of numerical values, and uses special image processing for the characteristics of the radar modulation mode, thereby improving the recognition accuracy.

Description

technical field [0001] The invention belongs to the technical field of radar. Specifically, it relates to an image-based radar signal waveform modulation method identification method, platform and medium. Background technique [0002] In modern warfare, electronic warfare is particularly important, and radar is an indispensable 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, after the radar detects the target radar radiation source signal, it is the key to the radar reconnaissance task to analyze and identify it. Only by accurately identifying the target radiation source signal can an effective analysis be made. At present, the identification of radar signal radiation sources is generally judged by the values ​​of characteristic pa...
