摘要
FIELD: radio engineering; detecting pseudorandom frequency hop/hopping signals to organize effective radio suppression of frequency hop/hopping line.;SUBSTANCE: frequency band extension is attained due to conversion of Δf0 operating frequency band into k-orthogonal intermediate-frequency channels, their integration into one code-multiplexed group frequency channel, n-selection of group frequency channel to obtain desired precision, and its decoding. Multichannel FH signal receiver has k-channels of first selection step and n-band filters of second selection step (8.1-8n). Each channel of first selection step has band filter (1.1-1.k), mixer (2.1-2.k), intermediate-frequency amplifier (3.1-3.k), heterodyne (4.1-4k), and modulator (5.1-5.k). Receiver also has orthogonal-sequence generator (6), decoupling device(7), and correlation matrix k x n (9).;EFFECT: enhanced probability of frequency hop/hopping signal detection due to extending simultaneous-survey frequency band at same precision, mass, and size.;1 cl, 2 dwg
