frequency 10 ghz # Ref 1, 8-12 ghz
# Because nothing was specified about the power (other than the fact that it has
# to be less than the 1.1 MW from the generator, which is also used for other needs)
# a real value cannot be defined. But something that so the model can compute a
# receiver noise power that results in a detection range of 1000 km.
#
# The actual power isn't important because passive detection of the transmitter is
# not being considered.
power 200 kw
# We don't know anything else about the transmitted signal (pulse width, PRF,
# pulse_compression), so nothing is supplied.

receiver
antenna_pattern BLUE_ABM_TTR_ANTENNA
# We don't know anything about the receiver (noise figure, etc.) The effective
# noise power is derived by the model to get the required nominal detection range.
#
# This will probably result in a ridiculously low effective noise power, but
# because we don't know anything about the transmitted signal modulation, we just
# have let it ride. It shouldn't be important because we aren't worried about jamming
# or passive detection.
