When the aircraft's sensors detect a threat, the countermeasure dispenser system automatically launches radiofrequency and infrared countermeasures at the optimum time to defeat incoming missiles. The ALE is compatible with a wide variety of countermeasures such as different types of flares and chaff. It is also designed to work with advanced ...
Spanish generally uses adjectives in a similar way to English and most other Indo-European languages. However, there are three key differences between English and Spanish adjectives. In Spanish, adjectives usually go after the noun they modify. The exception is when the writer/speaker is being slightly emphatic, or even poetic, about a ...
Contemporary radar systems can distinguish chaff from legitimate targets by measuring the Doppler effect; [4] chaff quickly loses speed after leaving an aircraft, and the resulting shift in wavelength of the radar return can be measured. To counter this, a chaff cloud can be illuminated by the defending vehicle with a doppler-corrected ...
Spanish verbs are a complex area of Spanish grammar, with many combinations of tenses, aspects and moods (up to fifty conjugated forms per verb).Although conjugation rules are relatively straightforward, a large number of verbs are irregular.
The most obvious differences between Spanish and Portuguese are in pronunciation. Mutual intelligibility is greater between the written languages than between the spoken forms. Compare, for example, the following sentences—roughly equivalent to the English proverb "A word to the wise is sufficient," or, a more literal translation, "To a good ...
Strictly speaking, the difference between them is one not of tense but of aspect, in a manner that is similar to that of the Slavic languages. However, within Spanish grammar, they are customarily called tenses. The difference between the preterite and the imperfect (and in certain cases, the perfect) is often hard to grasp for English speakers.
All varieties of Spanish distinguish between a "single-R" and a "double-R" phoneme. The single-R phoneme corresponds to the letter r written once (except when word-initial or following l, n, or s) and is pronounced as [ɾ], an alveolar flap—like American English tt in better—in virtually all dialects.
Chaff as a waste product from grain processing leads to a metaphorical use of the term, to refer to something seen as worthless. In the Bible, such use is found in Job 13:25, [13] Isaiah 33:11, [14] Psalm 83:13-15, [15] and other places. Chaff also lends its name to a radar countermeasure, composed of small particles dropped from an aircraft.
