band, and its range of 50 km is shorter than the detection range of
HFSWR. Therefore, only the tracking results with matched AIS
data were analyzed. Figure 11 shows the matched tracking results
in the latitude and longitude coordinate and R-D coordinates for
the three-channel array (red circles), the eight-channel array (blue
circles), and the AIS data (green circles).
To quantitatively analyze the detection performance of compact HFSWR, two tracking examples at different ranges were selected for analysis. Figure 12 shows the tracking result in the latitude and longitude coordinates, Figure 13 shows the results in the
range-velocity coordinates, and Figure 14 shows the change in the
three parameters over time for the two targets. Here, the green lines
represent AIS results, the red lines represent the tracking result using three-channel HFSWR, and blue lines represent the tracking
result using eight-channel HFSWR.
As seen from Figure 12a and Figure 13a, Target 1 is closer
to the HFSWR station, moving from 66 to 80 km from the station over 1 h. Its radial velocity varied from −10 to −14.5 km/h.
As can be seen from the measured AIS data, most vessels were
moving in straight lines. However, the tracks of the HFSWR are
