  • Woodman, Ronald (1960)
    A New Phase Measuring Technique has been developed as a solution to some of the present limitation of Minitrack Satellite Tracking System. Two main problems are solved, one concerned with the processing of the information ...
  • Woodman, R.F. (National Aeronautics and Space Administration, 1962-09)
    A variable-bandwidth filter has been designed and built to narrow the postdetection bandwidth of the Minitrack satellite tracking system. It is based on phase-lock techniques. Al its narrowest bandwidth, 0.03 cps, the phase ...
  • Woodman, Ronald (1963-07)
    This report will discuss the possibilities of using the Minitack system with a wider predetection Bandwidth in conjunction with the Narrow Band Tracking Filter for the tracking of Radio Stars.
  • Woodman, Ronald (1963-12-13)
    A combined system consisting of an Interferometer and a Range System has been proposed (Reference #1) for tracking the Apollo spacecraft during the re-entry phase. The system herein discussed processes the output of the ...
  • Woodman, Ronald (1964-01-17)
    The characteristics of a servo phase-lock tracking filter is described herein. The filter tracks a 100 cps carrier with a bandwidth of either 0.3 cps or 0.03 cps. The advantages of this type filter and its use is also discussed.
  • Spafford, Michael; Wiack, Richard; Woodman, Ronald (1965)
    A Rocket Interferometer Tracking (RIT) system is described. It uses a modified 108 Me Minitrack receiver converted for 73.6 Me operation and a newly developed phase measuring system. The output of the system is real time ...
  • Woodman, Ronald F. (1967)
    This thesis is concerned with the theory of incoherent scattering by a plas­ma, i.e., with the statistical description ofthe electromagnetic waves scattered by the thermal electron density fluctuations in a plasma which ...
  • Tisnado, G.; Woodman, R.; Pomalaza, J. (Instituto Geofísico del Perú, 1970)
    The 136 MHz interferometric system at the past NASA Satellite Track­ing Station in Ancón, Perú, consists of two orthogonal baselines aligned along the North-South and East-West directions. A sizable number of interferometric ...
  • Woodman, Ronald (1970-03-19)
    El avance que ha experimentado la humanidad en los últimos decenios se debe pura y exclusivamente a la investigación. Los avances científicos y tecnológicos que tanto nos impresionan se deben el mayor y mejor conocimiento ...
  • Woodman P., Ronald (Instituto Geofísico del Perú, 1970-09-08)
    La ciencia de la sismología nos permite determinar la magnitud y ubicación de un sismo con instrumentos remotos con toda la exactitud necesaria. Conocidas la ubicación y la magnitud se puede estimar los daños causados ...
  • Pomalaza, José; Woodman, Ronald F.; Tisnado, Gilberto; Sandoval, Jaime; Guillén, Alberto (1970-10)
    The purpose of this report is to present a preliminary analysis of the data collected in connection with NASA contract work with ESSA (ESSA contract No. E22-9-70(N)). Under this contract a study of equatorial ionospheric ...
  • Woodman, Ronald F.; Guillén, Alberto (Instituto Geofísico del Perú, 1971)
    A radar technique has been implemented at the Jicamarca Radar Observatory to measure winds in the upper atmosphere. Backscattered echoes of sufficient strength are recieved from stratospheric heights in the 20 to 30 km ...
  • Woodman, R.F. (1971)
    The purpose of this note is to report on a simpler device which has been constructed in our laboratory with the above purpose in mind. The construction of the device was motivated by our interest to see what effect would ...
  • Woodman, R. (1971-01-01)
    A technique to measure the direction of the geomagnetic field by using incoherent scatter techniques is described. The technique has been used to measure the inclination of the magnetic field at the Jicamarca Radar Observatory ...
  • Woodman P., Ronald (Instituto Geofísico del Perú, 1971-03-26)
    El Instituto Geofísico del Perú ha estado siempre conciente de la importancia económica de la Geofísica como ciencia a la ayuda de la prospección de recursos naturales. El reconocimiento re la importancia de los métodos ...
  • Woodman, Ronald F. (1971-04)
    The purpose of this note is to report on ionospheric observations taken at Jicamarca (lº N Magnetic Latitude) during the March 8, 1970 magnetic storm. This report includes measurements of the electron density, electron ...
  • Balsley, Ben B.; Woodman, Ronald F. (1971-10)
    This report is a collection of measurements of electrón drift velocity in the E and F regions of the equatorial ionosphere, made at the Jicamarca Radar Observatory (dip latitude ~1°N). The data consist of about eighty days ...
  • Kelley, M.C.; Gonzáles, C.; Mozer, F.S.; Woodman, R.F. (1972)
    Simultaneous balloon measurements of the auroral zone electric field in Alaska and of the vertical drift velocity of the region at Jicamarca, Peru during the great flow of August 1972 are presented.· The eastward electric ...
  • Guillén C., Alberto; Woodman, Ronald (Instituto Geofísico del Perú, Radio Observatorio de Jicamarca, 1972)
    Muchos procesos para su estudio óptimo por medio de computadoras requieren de diferentes sistemas de transducción. El presente trabajo describe el diseño de un sistema digital para acoplar un sistema de mul­plex y de ...
  • Pomalaza, José; Woodman, Ronald; Tisnado, Gilberto; Nakasone, Eduardo (Instituto Geofísico del Perú, 1972-12)
    Observations of amplitude scintillations produced by F-Region ionopheric irregularities has been performed at the Ancón observatory (Latitude - 11°46', longitude 77°9') since 1968. At first minitrack interferometric records ...
