2.3 DSTO Radar Dataset
From 1993 to 2008, the Defence Science and Technology Organization (DSTO) in
Australia conducted six shore-based and airborne radar measurement trails with three
radar bands (L, S and X bands), and datasets were constructed covering various data
types [12–18]. DSTO dataset supported several task background effectively. For
example, the L-band dataset was in support of SEA1448 [14], the ANZAC Anti-Ship
Missile Defence (ASMD) program. The S-band dataset was in support of the ANZAC
Anti-Ship Missile Defence (ASMD) upgrade project [13].
2.4 UCL Radar Dataset
In 2010 and 2011, trails were conducted within the collaboration between University
College London (UCL) and the University of Cape Town (UCT) to collect and analyze
data on multistatic sea clutter and maritime targets, using the S-band netted radar
system NetRAD. The system consists of three distinct, but essentially identical radar
nodes. GPS disciplined oscillators that have been developed by the University of Cape
Town were used to synchronize the nodes both in time and frequency. The marine
environment information during the trail was provided by the weather station nearby
[19, 20].
3 Construction of Marine Target Detection Dataset
3.1 Construction Framework
The overall framework of dataset construction can be decomposed into three closely
related and mutually supported modules (as shown in Fig. 2).
The first is detection equipment and data acquisition system, which mainly solves
the problem of data sources and storage. This module mainly includes radar detection
equipment (including multi-type experimental radars), satellite ground station and
photoelectric equipment, AIS and ADS-B equipment, high-speed data acquisition and
storage equipment, etc. What’s more, weather instrument, compass, GPS, laser rangefinder, wave buoy, multi-type standard reflector, sailing boat, rubber boat and other
auxiliary experimental facilities are also equipped.
The second is data management and processing module, including radar database,
auxiliary sensor database, and supported management and analysis software, so as to
manage various types of data more efficiently. In addition, a signal processing and data
processing platform composed of high-performance computers is also constructed in
this module to support the development and verification of algorithms, such as pulse
compression, STC, clutter suppression, CFAR, TBD, track initiation, data association
and track filtering.
The third is integrated display module, which mainly completes radar data display,
auxiliary sensor data display and comprehensive situation data display functions. It can
display AIS, ADS-B, electronic chart and other auxiliary information superimposed on
radar video, as well as the comprehensive situation of radar, photoelectricity, AIS and
other targets detected by multi-sensors.
