Fastandintensive development oftheresearches connected tostudying ofplasma formations inan atmosphere anda space,entails statement ofthe numerous problemsproviding successful realization ofthese researches. Tothese plasma environments many conceptsand the representations received ina courseoflaboratory researches which,thus,geta new field of application anduseareapplied. However, insome casesitisnecessarytolaydownspecial conditions at thejointdecision of theoretical and experimental jobsin,whichsolve theproblems arising during realization ofresearches designated above.The purpose of thegivenjobis experimental checkofsome results oftheoretical calculations on dispersion ofradio waves forward onthelaboratory modelsimulating aplasma trace behind spaceobject included inan atmosphere. Experiments were spentatthelaboratory stand including vacuum installation, working ina range ofpressurefromone tenth up tothousand Pascal's, high-frequency installation for generation ofairplasma at a currentofthe category from0,1up to10amperes,microwave measuring installation ina range oflengths of waves from3 up to 12 centimeters and instaDations forelectrical probesand other measurements ofparameters ofplasma. Along atrajectory ofan entrance ofa meteorin an atmosphere there isan ionization ofairand formation oftheplasma tracereflecting radio waves. Thefirst significant results on physics ofthe meteoric phenomenahavebeenreceived, for example, injobs(1-41. Thenextyear's development ofpractical useofmeteoric traces forthepurposes of a radiocommunication has involved many researchers inquestions ofthetheory ofdispersion of radio wavesfrom aplasma traceofa meteor.Inone
