Embodiment Construction

[0019] The technical solutions in the embodiments of the present invention will be further described in detail below in conjunction with the drawings in the embodiments of the present invention.

[0020] Such as figure 1 As shown, this example provides a labeling method for radar signal detection data samples, including:

[0021] Step 1: Select the data collected in an electromagnetic environment for manual analysis. The basis of manual analysis is to synchronously display the main parameters of the original detection data: frequency, pulse width, amplitude, time, azimuth, etc., through a visual interface. In this interface, the original detection data can be selected, and the selected The time difference is repeatedly calculated and drawn to assist in artificially discovering the correlation between the original detection data sequences;

[0022] Step 2: Select the sample data as the standard sample file. Professionals who are familiar with the characteristics of radar dat...

Abstract

The invention discloses a radar signal detection data sample labeling method, and mainly aims to solve the problems of high requirement on the quality of labeling personnel, large workload and low working efficiency in a mode of analyzing and extracting radar data one by one mainly through manual labeling in an existing sample labeling method. The method comprises the following steps: extracting effective data through visualization software for labeling, and storing the effective data as a standard sample file; and taking the standard file as a template, traversing and collecting an original data file, and automatically generating a new sample file. The method has the advantages that personnel with rich radar signal detection data analysis experience can concentrate on manually labeling data appearing for the first time; similar target data selection can be matched by adopting a similarity calculation method, although calculation is time-consuming, the calculation can be automaticallyrealized by a computer, and a large number of data samples can be extracted without consuming extra manpower.

Description

technical field [0001] The invention relates to the field of data processing of passive detection. Background technique [0002] With the rapid development of radar technology, the modulation characteristics of radar signal waveforms have been continuously improved. Traditional radar signal detection and identification methods mainly use radiation source database template matching. For more and more new system radars, these methods have low recognition rates. The accuracy rate is not high, and it is difficult to meet the technical requirements. The development of artificial intelligence technology provides a new processing method for radar recognition technology, using deep learning network to train data characteristic parameter values ​​to realize the recognition of radar signals. [0003] In the training process of deep learning, a large number of pre-labeled data samples are required as the training set. The existing sample labeling methods are mainly for pictures, imag...
