Abstract

The invention provides a transmitting system based on a rotary mechanical antenna and an information loading method. The method comprises: information is loaded to a frequency parameter for emitting electromagnetic waves through rotating speed regulation and control according to requirements of a signalling excitation signal; then through rotating speed detection and closed-loop feedback control,regulating and controlling the rotating speed of the rotating motor and the mechanical antenna fixedly connected with the rotating motor, and achieving frequency control of an emitted electromagneticwave; and driving the rotary mechanical antenna by the rotary motor to rotate around the center shaft at a high speed, transmitting electromagnetic waves with the same frequency as the rotating speedto the outside, receiving the transmitted electromagnetic wave signal by a receiving side, receiving information through frequency demodulation, and then achieving low-frequency radio long-distance communication.

Description

technical field [0001] The invention belongs to the technical field of low-frequency electromagnetic communication, and in particular relates to a signaling system and an information loading method based on a rotating mechanical antenna. Background technique [0002] Low frequency (Low frequency, LF) refers to radio waves with a frequency band from 300Hz to 30kHz, which can penetrate deep seawater and rock formations, propagate stably in the Earth-ionosphere waveguide, have low loss, and are basically not affected by nuclear explosions. It plays an irreplaceable role in applications such as long-distance submarine communication, underwater communication, ground-penetrating communication and minimum communication. [0003] Existing low-frequency transmitters are often equipped with very bulky transmitting antennas and high-power solid-state transmitters. The solid-state transmitter is used to provide high-voltage feed to the transmitting antenna to drive the free electrons i...
