The WSR-88Ds use a 10 cm radar wavelength, but the TDWRs use a much shorter 5 cm wavelength. This shorter wavelength allow the TDWRs to see details as small as 150 meters along the beam ...

The ability of radar to successfully detect targets and distinguish among them is also affected by the wavelength. A longer wavelength, which corresponds to a lower frequency, is typically less ...

There are seven members of electromagnetic family. The order of electromagnetic waves in the spectrum is shown in the table below.
