Ideal 1st and 2nd Trip Echoes
The ideal first and second trip echoes represent the echoes as they would appear
individually. The ideal 1st trip echo is the echo that would be measured if there were no
second trip echo interference. The ideal second trip echo represents what would be
measured if there were no 1st trip echo interference. If there is no interference from the other
trip, a standard Klystron system can measure the ideal spectra, but there is no way to know
whether the echoes are in the
first or second trip.
