Investigation of the internal structure of cometary nuclei by the use of spaceborne radio devices
Abstract
A spaceborne system is defined for collecting data on cometary nuclei; it consists of a high-precision 4-channel radar and 4-channel radio telescope operating in the 8 mm to 3 m range. The spacecraft will approach and circle the cometary nucleus at a radial distance of 1000 km and determine in-depth density distribution by measuring the permittivity and gas-phase states by means of in-depth kinetic temperature distributions utilizing data on cometary frequency spectra and thermal radiation. A television system produces images for determining cometary dimensions and possible heterogeneities and for integrating data. Available information is surveyed in order to select an appropriate comet for investigation and the bases for design of electronic equipment are discussed.
