Description

Technical Field

[0001] The present invention relates to the analysis of admission data. More specifically, it relates to a general analysis system and method for radar admission data. Background Art

[0002] In the prior art, the post-processing analysis of radar data is the main means of radar debugging, and its main function is to process and analyze the control data and echo data files recorded in real time by the radar. In the traditional method of post-processing analysis of radar data, since the admission data structures of each radar project are not unified, it is necessary to separately design and develop a post-processing analysis program based on Matlab. The advantage is that it is convenient for direct development and does not require the design of complex data parsing and cleaning logics. However, the disadvantages are also obvious. Matlab is slow in processing binary files and must re-change the program code to adapt to different radar projects, and it does not have good scalability.

[0003] In addition, with the continuous increase in the types, sampling rates, number of channels, etc. of radar admission data, the amount of data for post-processing analysis of radar data is increasing rapidly, and the traditional method of post-processing analysis of radar data cannot meet the requirements of processing time. Moreover, when performing post-processing analysis of radar data, it is necessary to first screen the admission data files according to radar waveforms, target numbers, etc. and extract valid data, all of which require updating the code according to the admission data structures of different radar projects, greatly increasing the later software development workload and maintenance cost. Summary of the Invention

[0004] To solve at least one of the above problems, the present invention provides a general analysis system for radar admission data. This method formulates a general admission data structure specification for radar admission data, provides general modules such as data parsing, frame header indexing, data screening, field extraction, waveform display, and Mat format conversion, solves the problems of slow processing speed and difficult expansion in the traditional method of post-processing analysis of radar data, and ultimately improves the reuse degree and processing efficiency of radar admission data analysis and reduces the software development workload and maintenance cost.

[0011] The field extraction module is used to extract each field of the current frame data transmitted by the analysis data structure configuration file and the file parsing module frame by frame, and save it as a text file for subsequent data analysis and processing.

[0056] A specific embodiment

[0057] A method for radar acquisition data, comprising:

[0058] Step 1, construct an acquisition data frame header, and according to the general acquisition data structure specification in Table 1 and the acquisition frame header structure specification in Table 2, fill 16 - word frame header information for each frame of acquisition data, including frame header flag, frame length, UTC time, waveform type and length;

[0059] Step 2, copy the control word or processing result, and according to the general acquisition data structure specification in Table 1, copy and fill fields such as the control word or processing result behind the 16 - word frame header;

[0060] Step 3, copy the waveform data, and according to the general acquisition data structure specification in Table 1, fill the waveform data at the end of each frame of data.

[0061] In a specific embodiment, the implementation manner of general analysis of radar acquisition data includes the following specific steps:

[0062] Step 1, define the acquisition data structure header file.

[0063] Write or reference the existing acquisition data structure.h header file according to the C - language programming specification and the acquisition data structure.

[0064] Step 2, implement the header file parsing module.

[0065] Write the specific implementation of the header file parsing module, which mainly completes reading and parsing the acquisition data structure definition header file written in Step 1, extracts the name, position, type, and length information of each field or data, and then saves it in xml format (generating 3 types of xml files, a configuration file for mat format conversion, an acquisition data structure configuration file for treeview display, and an analysis data structure configuration file for viewing fields frame - by - frame), facilitating the extraction of information of each field from the acquired binary file.

[0066] Step 3, implement the treeview display module.

[0067] Write the specific implementation of the treeview display module, which mainly completes reading and parsing the xml file and displaying the treeview structure tree. Realize the visual display of the acquisition data structure and support selection by dragging.

[0068] Step 4, implement the frame header index generation module.

[0069] Write the specific implementation of the frame header index generation module. This module mainly reads the radar binary recording file, automatically traverses and searches for the frame header flags of each data frame in the entire binary file, and then obtains the frame length and frame end position according to the information in the frame header. When an error occurs where the length information in the frame header is inconsistent with the actual frame length in the recording file, the error data is removed, the frame length is corrected to achieve data cleaning, and at the same time, the position and frame number of the error frame in the recording file are recorded, which is convenient for further analyzing the reason for the error in the recorded data in binary mode. At the same time, it can avoid subsequent multiple processing and analysis modules from producing incorrect results due to using incorrect data. At the same time, the frame header index generation module saves the starting offset position and frame data length of each frame of data after correction in the recording file in a separate *head frame index file for subsequent processing and analysis. The frame header index generation module only processes when the radar binary recording file is opened for the first time. When a *head frame index file already exists, it will not repeat the processing and generation of the frame header index file.

[0070] Step 5, implement the recording file parsing module.

[0071] Write the specific implementation of the recording file parsing module. This module mainly extracts the current frame data in the radar recording file according to the information in the frame index file.

[0072] Step 6, implement the field extraction module.

[0073] Write the specific implementation of the field extraction module. This module mainly extracts each field frame by frame according to the xml format recording data structure configuration file and the current frame data extracted by the file parsing module, and saves it as a text file for easy viewing and analysis of the recorded data;

[0074] Step 7, implement the binary viewing module.

[0075] Write the specific implementation of the binary viewing module. This module mainly views the original recording file in binary format according to the current frame data extracted by the file parsing module, which is convenient for positioning and analyzing problems in the original data in cooperation with the field extraction module.

[0076] Step 8, implement the waveform plotting module.

[0077] Write the specific implementation of the waveform plotting. This module mainly obtains parameters such as the format, data width, length, and step size of the waveform data according to the current frame data extracted by the file parsing module, the waveform format in the frame header, and the waveform plotting parameter configuration file, and then performs curve plotting, and supports functions such as waveform zooming, restoration, and translation.

[0078] Step 9, implement the data screening module.

[0079] Write the specific implementation of the data screening module, which mainly completes the comparison frame by frame in the admission file according to the value range of multiple fields, retrieves the data frames that meet the screening conditions, and saves them separately as files for subsequent data processing and analysis.

[0080] Step 10, implement the mat format conversion module.

[0081] Write the specific implementation of the mat format conversion module, which mainly completes the conversion of each field and waveform data into the mat format by calling the engine of matlab and saves them separately as files for subsequent data analysis and processing.
