RADIO ASTRONOMY STATUS REPT. NO. 23, JUNE 1, 1953
Abstract
Progress is reported on research in radio astronomy which includes an investigation of the noise and wave-propagation characteristics of the stratosphere to determine the limitations on electronic methods for tracking and searching objects. A simple technique is presented for determining the effect of changing the assumed electron density by any constant factor on calculated radial brightness distributions. A preliminary value of 8.5x105 deg K for the temperature of the quietsun was deduced from measurement sat 200 mc with a 5-mc bandwidth. The program for determing 200-mc burst-source position lines for 60 active days from August to December 1952 was completed. A method was developed to determine position lines of sources of excess base level from simultaneous recordings with a radio telescope and radio interferometer. Equipment and procedure changes are described for the interferometer, 200-mc receivers, coaxial switches, azimuth markers, an automatic recorder switch, and an hour-angle computer. A brief description is included of the papers presented on radio astronomy to the joint URSI-IRE meeting in Washington, April 27 to 30, 1953.
