An advanced, inexpensive, transportable radar meteor trail set was developed and was recommended as an international standard by IUCSTP at the Moscow 1971 COSPAR meeting. The interferometer height-measuring technique, tested with the CRLH 001 Beacon in satellite OV1-17, was also recommended because of ground calibration capability and achieved accuracy. Computer programs for data reduction and advanced analysis were used to reduce and study wind and density data from AFCRL, Eglin AFB, Stanford University and the University of New Hampshire. Results were compared with other investigators' findings. (Author).

A description of the data taken at AFCRL from 1964 through 1966 and the methods of analyzing the wind data are presented. A least squares fit to the mean, 24-hr, and 12-hr components of the wind was applied to the data, and the results are compared to those obtained by other investigators. (Author).

The Stanford University Mark II Radar Meteor Trail System was moved to Eglin AFB, Florida for field testing and to make comparison of winds obtained by the rocket, chemical release method and the radar meteor method. Recommendations for locating and maintaining meteor radar systems, as well as modifications for the Mark II system suggested by the aircraft and satellite calibrations and by operating experience, are given.

Columns of ions left by the passage of meteors through the 80- to 100-km altitude region are used as tracers to monitor the wind and density variations of the high atmosphere. Recent equipment development with pulse-interferometers operating in the 20- to 75-MHz band has made it possible to obtain more accurate information on the location of the reflection point on the ionized meteor trail. Analyses of the wind and density data obtained at AFCRL, at Stanford, California, Durham, New Hampshire, and Eglin AFB, Florida are reviewed. Rocket and meteor trail wind observations were obtained at Eglin AFB and, for a separation of 150 km, show reasonable comparisons within one hour. Poor comparisons at larger space and time separations are attributed to large-scale horizontal eddies (gravity waves). (Author Modified Abstract).

In the study of upper-atmosphere winds and densities, radar measurements of the ionized trails of meteors in the height region between 80 and 110 km have proven valuable. In the present report, this measurement technique is compared to other methods and its advantages and problems are outlined. Considerations for the design of a meteor-trail radar system are presented. The desire for a global network of meteor-trail radar stations, which would aid significantly in the study of synoptic atmospheric patterns, calls for a reliable, simple, and inexpensive design. Such a design, realized at Stanford University and tested in operation, is described in detail. Data are recorded automatically on digital magnetic tape and are reduced completely by computer; except for tape changes, the station operates unattended. Circuit diagrams, assembly, and tuning procedures for the complete station are presented, and the computer program used for data reduction is listed. The equipment was built on printed circuit cards for which negatives are available, on request, from Stanford University. (Author).
