Tracking singlehander sailboats, 1Km mode

A prototype Navtech CIR radar was modified to enable an instrumented range of 1Km. This new operation mode is available on request, and is accessed as a user-selectable profile in the Vertex web interface.

The 1Km mode is realised by modifying the 77GHz FMCW output, the range bin is increased from 17.5cm to 29.2cm, yielding an overall radar range increase from 600m to 1Km using 3424 bins.

Example Dataset 1:

The prototype radar mode was used to survey numerous small sailboats and RIBS travelling around a reservoir. The .colraw file below is a radar dataset containing the movements of these boats, and includes a pedestrian carrying a large 1200m2 corner cube reflector detected moving along the southern perimeter wall at a range of 1Km.
