He pointed to the gadgetry that controlled the radar wavelength.

With velocities of less than 70-metre/second for weather echos and radar wavelength of 10 cm, this amounts to a change only 0.1 ppm.

These are copper nickel-coated glass fibers or silver-coated nylon fibers having lengths equal to half of the anticipated radar wavelength.

The radar wavelengths are still jammed, the fade-out on the TV and radio wavelengths has got worse.

About half an hour before we got word that radar wavelengths had been hit by the fade-out.

The Russians had the same system, but with different codes responding to different radar wavelengths.

If the radar wavelength is roughly twice the size of the target, a half-wave resonance effect can still generate a significant return.

Improving the resolution of an imaging radar requires that the antenna size is many times that of the radar wavelength.

At long radar wavelengths, a harmonic wave is something like seven feet long, which may coincide with the natural frequency of something on the missile.

Radar uses electromagnetic radiation with microwave frequencies; the atmospheric absorption at typical radar wavelengths is very low, meaning observations are not prevented by cloud cover.
