This radar data was collected by a system in Goose
Bay, Labrador. This system consists of a phased
array of 16 high-frequency antennas with a total
transmitted power on the order of 6.4 kilowatts.
The targets were free electrons in the ionosphere.
"Good" radar returns are those showing evidence
of some type of structure in the ionosphere.
"Bad" returns are those that do not; their signals
pass through the ionosphere. Received signals
were processed using an autocorrelation function
whose arguments are the time of a pulse and the
pulse number. There were 17 pulse numbers for the
Goose Bay system. Instances in this databse are
described by 2 attributes per pulse number,
corresponding to the complex values returned by
the function resulting from the complex
electromagnetic signal.
Number of Instances: 351
Number of Attributes: 34, All 34 are continuous,
as described above
This is a binary classification task.
