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 ...

Stealth aircraft require antennas that minimize radar detectability while maintaining ... height—up to 0.39 times the low-frequency wavelength—which presented a trade-off between stealth ...
