Аннотация

A technique for estimating the velocity of radio meteors is proposed. The presented method is based on the analysis of the phase of the Fourier spectra of complex amplitudes of signals reflected from meteor trails. The method is very fast compared to the Fresnel transform method, works at low signal-to-noise ratios and is automatic. Approaches for increasing the signal-to-noise ratio and criteria for rejecting the obtained estimates are proposed. An error of 1-10\% was achieved, depending on the signal-to-noise ratio (from -5 dB) and the velocity of the meteor. A comparison of the velocities of meteor showers using measurements in Kazan with optical observations revealed a good agreement of estimates with a slight underestimation of 2-8\%, presumably due to the neglect of deceleration.
