DEVELOPMENT AND STUDYING OF THE CHANNEL FOR FORCED TUNING OF THE DOPPLER TRACKING FILTER OF THE FM-SIGNAL, REFLECTED FROM A SUBSTRATE SURFACE

摘要

Suitable for practical implementation mechanical frequency tuning channel of the Doppler tracking filter with injection-locked control oscillator is synthesized. A theoretical description, filter functional scheme, design and implementation method of frequency discriminator, providing significantly better parametric performance as compared to the existing ones and approximately the same fluctuation error under filtration coefficient K_F>15 ÷ 20 are presented. The basic analytic relations useful for analytical calculations, as well as the results of computer simulation of the synthesized channel of mechanical frequency tuning channel of the Doppler tracking filter are provided.
