Test Targets
The Test Target facility provides a simulation that allows data to be entered
for a test target that can then be tracked by the system. The tracked data
can be used to compare with the test target data to assess the
performance of the tracking system.
Test targets include fixed test pattern targets
and a number of moveable test targets. The
facility is available in all presentation and
motion modes, providing the system has a
working compass and is in Transmit mode.
Test targets can be displayed and tracked in
exactly the same manner as live targets,
although the system differentiates between
test targets and tracked real targets.
Both fixed and moveable test targets are
displayed on the screen as flashing green
crosses. When test targets are on a large
stationary letter
X is displayed near the bottom
of the video circle.
The Test Targets window is divided into the
following areas:

Fixed Test Targets
 Moveable Test Targets
Fixed Test Targets
The Fixed Test Targets area includes a Display check box. When this
check box is ticked, test targets, which are stationary relative to own ship,
are displayed on the video circle.
The targets are generated every 45 degrees starting at 0 degrees relative
to own ship’s heading and increasing in 2 NM increments to 40 NM. The
targets are a fixed size in both azimuth and range.
