Keyword(s):

The method that uses known satellite orbital parameters to generate antenna pointing angles [17].

Keyword(s):

Waves traveling through a medium [10].

Keyword(s):

Signal characterized by a steep rise from and decay toward an initial level [9] [12].

PULSE DURATION (PD)—The period of time during which a pulse is present [12].

Keyword(s):

A form of modulation in which one of the characteristics of a pulse train is
varied [12].
