DETERMINATION OF THE PARAMETERS OF ATMOSPHERIC GAS CLOUDS BY RADAR METHODS AT FREQUENCIES IN THE ROTATIONAL SPECTRUM

An analysis is made of a method of determining the parameters and coor dinates of atmospheric gas clouds radar systems which can measure the attenuation of electromagnetic radiation power at a resonant absorptio n frequency. A possible technical application of these systems is indi cated. This approach to the problem of controlling and monitoring the state of the atmosphere can describe the propagation dynamics of conta mination in real time, which is extremely important for ensuring safet y in regions liable to chemical contamination. After suitable developm ent the proposed method may provide the basis for remote monitoring by radar techniques and in principle, may also be used to study various types of nonreflecting objects possessing the property of resonant abs orption.
