Since K-Band frequency is 2.5 times higher than X-Band, the multipath signal generated by an intruder is also 2.5 times higher, vastly improving detection of slow and fast-moving targets.

因为K波段比x波段高2.5倍，由干扰产生的多信道信号频率也要高2.5倍，这极大改善了对慢速和快速移动目标的探测。

FORBES: Opportunities to fight for

The Republicans celebrated last month's triumph by fast-tracking several K-Street favourites: exempting older coal-fired plants from new anti-pollution rules, and making it easier to open national forests to logging and drilling.

ECONOMIST: The only people who could stop a Bush second term

Others learned early that equations beat etchings (picture book writers, once considered the "academicians of the nursery, " have been trampled on the fast track to pre-K).
