Abstract
The imitational model for the low-frequency satellite communication system has been developed using Simulink Ver. 8.2 (MATLAB) environment. The imitational modeling has been carried out for the signal reception with carrier frequencies in f0 ≈ 0 30 MHz…1 GHz range and with both single antenna (n=1) and diversified (n=2, 4, 8 antennas) signal reception. On this basis, the dependency of energetic concealment coefficient on the carrier frequency selection has been determined. The analysis of the obtained dependencies shows that in the lowered frequency range (f0≈ 30 MHz … 100 MHz) it is possible to increase the energetic concealment coefficient by γe(2) ≈ 24 dB when using the dual antenna reception system and up to γe(8) ≈ 42 dB when the signal is received by 8 antennas.
