cosecant-squared pattern

cosecant-squared pattern

[kō′sē‚kant ¦skwerd ′pad·ərn]
(electromagnetism)
A ground radar-antenna radiation pattern that sends less power to nearby objects than to those farther away in the same sector; the field intensity varies as the square of the cosecant of the elevation angle.
