The present invention maintains and increases the reception efficiency of the satellite signal by enabling the position correction of the sub reflector from the main reflector, and the position of the sub reflector can be changed so that it can be applied to both main reflectors having different sizes or curvatures. The present invention relates to a satellite signal receiving apparatus and a satellite signal receiving method.

In general, a parabolic antenna is used for reception of a satellite signal. The parabolic antenna is a directional antenna using a parabolic surface on a reflective surface, and can transmit and receive a satellite signal in a certain direction, and gain and efficiency aspects. It is excellent in, and therefore is used for communication using satellite or reception of satellite broadcasting.

In the case of satellite broadcasting reception, when a satellite located on a stationary orbit above the equator relays the broadcast signal emitted from the terrestrial broadcasting station and re-launchs it to the ground, the satellite broadcasting reception antenna installed in each home receives it. It transmits to the satellite receiver connected to it so that viewers can watch the satellite broadcasting through the TV receiver, and it can get clear picture and perfect sound without a blind spot within a certain frequency range, so it is getting the spotlight from viewers day by day. In recent years, however, it is widely used in general homes, and such satellite broadcasting generally requires an appropriate receiver for receiving SHF (Super High Frequency) frequency signals in the range of 3 to 13 GHz, and existing VHF (Very High at 3 to 30 MHz). Frequency, strength of radio waves on the ground compared to Ultra High Frequency (UHF) radio waves of 30 MHz to 3 GHz To the very weak because of the rain, the effects of clouds, dry matter, the quality of the receiving antenna is needed, such as to have the characteristics of the affected trees to get a good picture parabolic antenna.

In addition, in the case of communication using satellite, the radio wave has high linearity due to the use of high frequency in the microwave frequency band, and thus requires a highly directional parabolic antenna and the like, and unlike a fixed antenna such as a satellite earth station or a home, A tracking function is needed to track the position of the target satellite as the movement moves.

Referring to the accompanying drawings, a satellite signal receiving antenna according to the prior art is as follows.

FIG. 2 is a side view illustrating an antenna for receiving a satellite signal according to another exemplary embodiment, and shows an example of an antenna for satellite communication, using “sub-reflection plate rotation period correction” of Patent Registration No. 0599610, filed and registered with the Korean Intellectual Property Office. Satellite tracking antenna system and satellite tracking method. As shown in the drawing, a conventional antenna for receiving a satellite signal focuses a reflecting plate 310 for receiving a predetermined satellite signal in the direction of a target satellite and a satellite signal reflected from the reflecting plate 310 with an incoming waveguide 340. A sub-reflection plate 320, an absolute position measuring bar 321 installed at the sub-reflection plate 320 to measure a rotation period, a sub-reflection plate rotating part 330 for rotating the sub-reflection plate 320 at high speed, Detecting means 331 installed in the sub-reflection plate rotating unit 330 for generating an interrupt signal each time the absolute position measuring bar 321 passes, and shaping the satellite signal beam focused on the sub-reflection plate 320.

The satellite signal receiving method according to the present invention largely includes a waveguide installation step, a sub-reflection plate installation step, and a reception optimization step.

The waveguide installation step is to fix and install the waveguide 120 for the transmission of satellite signals in the center of the main reflector 110. In this case, the waveguide 120 is preferably installed vertically to face the focus of the main reflector 110 at the center of the main reflector 110.

In the step of installing the sub-reflective plate, the position of the sub-reflective plate 130 for re-reflecting the satellite signal reflected from the main reflective plate 110 to be introduced into the waveguide 120 is adjusted by the position correction means 140 with the main reflective plate 110. It is a step of installing at the inlet side of the waveguide 120 to enable.

The reception optimization step is to fix the satellite reflecting to the waveguide 120 at the maximum position by moving the sub reflector 130. The sub reflector 130 may be moved by implementing various methods. In the embodiment, as shown in Figure 5 by the rotation amount of the position correction means 140, that is, the screw coupling member 141, the sub-reflection plate 130 is moved on the central axis of the main reflection plate 110, the satellite signal The sub-reflective plate 130 is positioned at an optimal point for maintaining or improving the reception efficiency of the sub-reflective plate 130. At this time, the screw coupling member 141 is tightened by the fixing bolt 144 to the main body of the waveguide 120. The sub-reflection plate 130 is fixed by being fixed to the 121.

The reception optimization step is introduced into the waveguide 120 with the movement of the sub-reflective plate 130 by changing the length of the waveguide 120 whose length is adjusted by tightening and loosening by coupling the length adjusting tube 121a to one side. The satellite signal can be maximized.

On the other hand, the position at which the sub-reflection plate 130 is the maximum satellite signal introduced into the waveguide 120 may vary depending on the curvature, structure, size, etc. of the main reflection plate 110, the main reflection plate 110 is parabolic It is preferable to be located at the focal point.

When the sub reflector 130 is fixed, the satellite signal transmitted from the satellite is reflected by the main reflector 110 and is incident on the sub reflector 130 positioned at the focal point, and the incident satellite signal is reflected back to the sub reflector 130. Then, the waveguide 120 enters the waveguide 120 and is incident to the LNB through the reception hole 112 to be converted into an IF (Intermediate Frequency) signal, and received by the receiver in a state in which miscellaneous signals and noise are removed.

At this time, the sub-reflection plate 130 is tilted with respect to the rotation axis 132 and rotated by the rotation motor 131, so that the sub-reflection plate 130 is tilted in up, down, left, and right directions. By comparing the strengths with each other by the control unit, it is possible to know in which direction the main reflector 110 is biased with respect to the target satellite, and generate a position correction signal based on the difference value of the satellite signals to correspond to the main reflector. By allowing the 110 to rotate or / and move toward the target satellite, the satellite signal reception efficiency of the main reflector 110 is increased.

In addition, the sub reflector 130 is located in front of the main reflector 110, and has a structure for introducing the satellite signal into the waveguide 120 fixed to the reflecting surface 111 of the main reflector 110, a component unit such as LNB Since it does not need to be disposed in front of the main reflector 110, it contributes to reducing the size of the antenna and increasing the reception efficiency.

In addition, the position reflection of the sub-reflective plate 130 is possible by the position correction means 140 and the length of the waveguide 120 can be adjusted by the length adjusting tube 121a. Even the main reflector can be easily installed and applied.
