Assuming you mean the wavelength: Radar can use electromagnetic waves of VERY different frequencies; see this section of "Radar" in Wikipedia: https://en.wikipedia.org/wiki/Radar#Frequency_bandsThe list also includes the corresponding wavelengths; or you can divide the speed of light by the frequency.
A wavelength is the length between the crests (the top of the waves). This picture shows a good example: http://www.bom.gov.au/weather/radar/about/images/wavelength.gif

Using an imaging radar. Also known as Synthetic Aperture Radar (SAR).

Radar sends out a radio wave and measures the reflected radio wave using it to calculate a target's speed, shape, material the object is made of, and direction of movement.
CW in reference to radar usually means Continuous Wave. (CW Radar = Continuous Wave Radar) I don't think that it is usually referred to in a case sensitive way. You will need to explain the context better. Continuous Wave Radar references a radar system in which the transmitter is never turned off. The target illuminating, radio frequency emitter power is non-stop and unbroken. Isolation between the transmitter and receiver has to be specially considered during design.
Radar stands for RAdio Detection And Ranging. So ... radio.
When you shorten the wave length, you increase the amplitude.

radars are of two types pulsed and continuous wave radar. pulsed radar has its carrier pulse modulated used for detecting stationary objects continuous radar uses direct sine wave for transmitting and is used for moving targets there are types such as weather, and aircraft.
Ultraviolet has the longer wave length Infrared has the lower wave length
