A theoretical study of the integral radio emission of the moon, measured at the wave-length of 3·2 cm. (Zelinskaja and Troitzky[1]; Kajdanovsky, Turusbekov and Khaikin[2]), was carried out at the Gorky radio astronomical station ‘Zimenky’ and at the Physical Institute of the Academy of Sciences of the U.S.S.R. The following expression for the average radio temperature of the entire lunar disk, as a function of the lunar phase, Ωt, was obtained (Troitzky, 1954) [3]: Here tan ξ = δ/(1 + δ) and δ = β/κ, where β is the attenuation coefficient of the thermal wave, κ the power attenuation coefficient of the radio wave. Further, Tm = 374°K. is the temperature of the subsolar point, Tn is the temperature at the lunar midnight, Θ = Tm – Tn and k0 is the reflexion coefficient of radio waves for vertical incidence (k0 ≈ 0–1). The numerical coefficients in equation (1) were obtained as a result of averaging the Fresnel reflexion coefficients over the whole disk. The degree of polarization of the total radio emission was calculated and was found to be about 4 %.

Absolute Measurements

The absolute measurements of the intensity of radio emission of the Moon, carried out with the aid of more advanced equipment and method of calibration, made it possible to reveal its variation with the phase, and yielded the value of the effective temperature for the centre of the disk practically equal toT1= 245° + 15·5° cos(Ωt−50°), the ratio of penetration depth of the electric wave to the thermal wave equal to 6·0, and δ/λ = 2·0.

Good Agreement

The aim of this communication is to present the results of an experimental research on the intensity of the radio emission of the Moon at 4 mm and to describe the method followed in observations and reductions. It was established that the radio brightness of the Moon,Tl, varies during the lunation according to the law:Tl= 230° + 73° cos (Ω0t-24°)K. The accuracy in measuring the absolute value of Moon's radio temperature is about ± 10%. The comparison between the phase dependence of the radio emission of the Moon at 4 mm and the data from observations of the radio temperature of the lunar disk on other wave lengths demonstrated that the homogeneous model of Moon's surface is in good agreement with the experimental data.

The investigations of intensity and phase dependence of the thermal radiation of the Moon at various wave lengths of the radio-range are very important for clarifying the properties and structure of the Moon's surface layer.

Selection Of

In order to use the data on the radio emission of the Moon as a basis for conclusions regarding the characteristics of the surface layer of the lunar crust, additional data or assumptions about the properties of this layer are necessary. The use of high-resolution radio telescopes reduces to a certain extent the unavoidable arbitrariness in the selection of parameters. Observations with the 22-m radio telescope of the Physics Institute, Academy of Sciences, made it possible to evaluate certain characteristics of the surface layer without relying entirely on optical data.

Recently experimental data have been obtained on lunar radio emission which enable one to solve the problem as to which model of structure for its upper layer corresponds to reality: single layer (homogeneous structure of the covering) or a widely distributed two-layer-dust cover [1]. They also enable one to draw more definite conclusions as to the physical properties, thermal conditions, and structure of lunar material.
