THEORETICAL INVESTIGATIONS AND DESIGN STUDIES FOR THE EVENTUAL CONSTRUCTION OF A MEASURING DEVICE IN THE FIELD OF PLASMA ELECTRONICS. PART II. CORRECTION OF ANGULAR AND RANGE ERRORS
Abstract
Path ray and phase-transit time of a pla e electromagnetic wave penetrating a cylindrical plasma zero < epsilon < 1 are determined by analogy with optics by means of a geometric-optical approximation. With a parabolic distribution of the electron density, the solution obtained by calcul tion yiel s simple formulations of the phase-transit time and the angle of the ray path. Range errors and angular errors for the rays penetrating the plasma cylinder near th symmetry axis are calculated for parabolic distribution of electron density, and compared with the values obtained by experiment. If the distribution of the electron density is not known, a method of approximation is used permitting the determination of the response of the phase front behind the plasma cylinder, and consequently of the angular error. The graphic representations show the relationship between the path parameters of a ray and the measured values of the absolute phase-transit-time difference and the relative phase-transit-time difference.
