| Zusammenfassung |
A sky temperature map at
45 MHz covering declination between + 30° and + 60° is presented. The
sampling in right ascension is 20 min (~5°) and 2° in declination in
most of the map. The originality of the work was to use cosmic emission
measurements from five VHF Stratosphere-Troposphere (ST) radars collected
during long periods of routine meteorological surveys. This map, which has an
accuracy in temperature of about 600 K, is intended first for radar
reflectivity calibration and system performance monitoring. The presence of two
strong radio sources, Cassiopeia A and Cygnus A, can also serve as the
verification of the beam diagram, beam width, and beam pointing direction of
the antenna. Finally, this work is an attempt to show the potentiality of ST
radar for astronomical purposes.
