Radio Images of the Moon in the 8-Millimeter Range USSR.
Abstract
This communication concerns the two-dimensional distribution of radio brightness of the moon in the 8-mm range as observed by the 22 meter radiotelescope of the Physical Institute. The phase character of the distribution is disclosed; it follows with a shift of about 300, the changing phases of the moon. A darkening of the limb was also observed. From September to November 1959 systematic observation of the two-dimensional distribution of temperature brightness of heat radiation from the moon in the 8 mm wave range was carried out using the 22 meter radio telescope of the Physical Institute imeni P. N. Lebedev, AS USSR. Unlike all other known observations of moon radiation, including those in the same range, /1, 2/ where average data "smeared" over the disc temperatures were obtained, our observations, because of the high resolving power of our radioteelescope directional diagram at half-power level of about 2' X 2' yielded values of temperature brightness for particular areas on the lunar disk. Radio images of the moon were recorded with successive passages of the moon long the aximuth or height with simultaneous following or slow passage of another coordinate. Preliminary processing of the data obtained (uncorrected for some averaging due to the final width of the directional diagram of the radiotelescope antenna) permits the conclusions that there is a noticeable depedence of the radio brightness distribution over the lunar disk on the lunar phase.
