Signal strength records of stations IX-209 and IK-252 of Project 32.8 are
presented in Figs. 7.37 and 7.38, since the similar frequencies, 233.5 mc and
235.0 wc, and zero-rime positions contribute significaatly to interpretation of
che atteoguation data.
Figure 7.39 is a composite plot of borizontal rarge from ground zero, altitude, aod RF signal attemiation versus time of TK-205, MK-252, and the Teak HiLo rockets.
Figure 7.40 is a representation of these same data with attenuation
at given times tabulated on the flight trajectories.
Figure 7.41 is a plot of
Orange trajectories with attenuation at given times plotted on ths curves.

CONCLUSIQNS ©
The difficulty of reduciog the MIDOT tracking data for the Hi-Lo rockets
required that additional test rounds be fired in orlcur ta give better theorerical estimates of the trajectories.
A series of Deacon-Arrow rockets were firzcd
at Poict Arguelio, California, early in 1961.
These sea level lauachings re-
sulted in the trajectories used in Figs. 7.39 and 7.40 and agree well with the
attemuatioa data.
The systems used for this project have accuracies of about 3 db, and data
variations within these limits should not be interpreted as significant.
Attenuation due to ionization as a function of time must be determined
with regard to rocket position.
To arrive at generalizations without entering
the physics of ion recombination is somewhat difficule.
It appears that the
following statements can be nade>
*
Blackout is defined as receiver noise level, approzinatély 50 db down
from receiver saturation.
