ABSTRACT: The authors describe the theory, difficulties and results of wind observa-
tions based upon a combined (doppler-coordinate) doppler tracking method previously
described by them in detail elsewhere (avtorskoye svidetel'stvo NR 157,465 of looctW
The doppler method, based upon frequency shift of the signal reflected from an air-
borne targer has the advantages of high precision and continuous registration. A com-
bination of doppler and coordinate tracking methods appears therefore promising. Expe-
rience showed, however, that pendulous oscillations of suspended reflectors created
overwhelming velocity signal-noise. Therefor, solid symmetric freely dropped reflector
targets were adopted. A theoretical study points to the need of high angular res6lu.
tion and a small range of altitude elevation angles. This results in long range tra-

.cking requirement with related requirements of,effective reflectors and optimized ra-
dar frequencies and.pulse.repetition rates. Results of 12 reflector drops in the Fall
and Winter of 1963 are given, with relative wind velocity pulsations plotted for vari-
ous altitudes and wind velocities.-The RMS wind pulsations reach a maximum of 4% at
400 meters and remain close to 2% between the altitudes of 3 to 12 km. The relative
pulsations are practically independent of wind velocity at all altitudes studied. The
reflector sinking velocities were fairly constant and reached 4.15 - 4.35m/s at the
ground. The time delay constant of target acquisition of the wind velocity was between
.5 and 1,0 seconds, Uniting the registered granularity to 5 - 10 meters. The good re
solution of the method based on combined doppler and coordinate tracking opens new
possibilities for the study of wind structure. Preliminary results point to the pre-
sence of a complex mesostructure of the wind field. Orig, art, has: 5 figures, 2 tab-
les and a formulas.
