Satellite-oriented error angle detector for satellite tracking and detection method using same

摘要

The present invention relates to a satellite-oriented error-angle detecting device for satellite tracking and a detection method using the same, and more particularly, to a four-divided microstrip array antenna for synthesizing radio waves from satellites in phase and outputting them in four directions, A plurality of phase shifters connected to the low noise amplifier for determining a phase of an input signal; a power combiner for combining the signals of the phase shifter; A channel selector for selecting one of the signals output from the frequency down converter, a signal detector for converting the analog voltage into a voltage according to the magnitude of the selected one channel input signal, An A / D converter for receiving and converting the digital signal into a digital signal, And an azimuth angle and an azimuth angle of the satellite using the initial information such as the size of the signal detected by the signal detector, the current azimuth and elevation angle information output from the satellite tracking processor, and the beam pattern information of the antenna, A beam switching phase and a satellite-oriented error calculation controller for calculating an elevation angle error and outputting it to the satellite tracking processor, and outputting a phase control signal to the phase shifter. In a simple structure, An angle error angle is detected.
