At present, measurement trials have been jointly organized and carried out with
industrial departments such as No. 23 Institute of the Second Academy CASIC,
No. 38 and No. 22 CETC, AVIC LEIHUA electronic technology research institute.
Preliminary marine target detection dataset with various platforms, sea areas, sea states,
and target types, are constructed, including sea clutter property cognition dataset,
clutter suppression and target detection dataset, target characteristics dataset and
detection performance evaluation dataset. In the future, the trials will continue to enrich
the experimental data in a large diversity of conditions such as sea areas, sea states,
radar working frequencies and many others, so as to make it more practical for
intelligent radar applications.
3.2 Dataset Management
The massive datasets obtained through long-term and systematic trials are various and
inconvenient to query. In order to manage them more effectively, management software
based on Windows architecture server and SQL database version is developed, so as to
provide a more efficient data support for intelligent radar. In the software, all radar data
and auxiliary sensor data are associated and stored, and detailed information related to
the trials is recorded. Data classification and retrieval function is also realized. The
software can be connected with SQL database to manage off-line radar data. It can also
be connected with radar data acquisition system through data format conversion and
data transmission protocol, thus storing the collected data to the database in real time.
The software system design follows the principle of modular, structured and
reusability. According to the data processing procedure, the system can be divided into
five layers.
The first layer is information import section. It mainly includes five sub-layers
information, namely the trial information, radar information, weather information, sea
state information and target information. These sub-layers are used to record various
levels of data related to the trial, respectively, so as to facilitate the association with
subsequent radar data.
The second layer is data import section, which takes the radar data as main index.
When importing radar data files, the information layer data, target position, AIS,
optical, infrared and satellite image data as well as program documents and processing
results are synchronously imported for time synchronization and associated storage
with the main index.
The third layer is query setting section, which realizes the separate or joint retrieval
according to the test date, radar model, scanning mode, weather, sea state, target type
and other categories to improve the retrieval efficiency.
The fourth layer is display of query results. According to the query conditions set in
the third layer, the list of all data meeting the conditions is displayed, and the auxiliary
sensor data, program documents and existing analysis results associated with the main
index (radar data) are displayed synchronously.
The fifth layer is data preview and export section. After the specific item is selected
in the query result, the frame header details of radar echo data will be displayed, and the
export menu will be added in the right-click menu for the export of all data associated
with the current item.
