Which type of radar technology is less susceptible to interference from weather conditions?

Ka-band radar technology is the correct answer because it operates at a frequency range that is less affected by atmospheric conditions compared to other radar bands. While each radar band has its own characteristics, the Ka-band's higher frequency can allow for better penetration through certain weather phenomena, such as rain or fog, which can affect lower frequency bands like X-band and K-band.

X-band and K-band radars, being lower in frequency, are more susceptible to interference from various weather elements. For instance, heavy rain or thick fog can scatter signals from these lower bands, degrading their performance and accuracy. This makes them less reliable under adverse weather conditions.

Ultra-wideband radar technology, although versatile and effective in its own right, may not be as focused as Ka-band technology for speed detection purposes. It tends to be used in different applications, such as imaging and communications, rather than for detecting speed in law enforcement.

The unique properties of Ka-band radar, particularly its resilience to weather interference, make it a preferred choice in many traffic enforcement contexts.
