摘要： A receiving antenna apparatus for receiving broadcast by satellite and adapted for mounting on a mobile body in which radio wave interruption tends to occur by obstacles, attains high-speed automatic tracking function capable of catching the satellite again in a short time just after cutting off of radio waves. In the receiving antenna apparatus, an incoming direction of radio waves is roughly detected to limit a search area and then a gain of the tuners is reduced to a value in the tracking control capable of detecting a peak and confirming a main lobe in accordance with power level of the received signal, so that a narrow and fine search may be made only in the limited search area. The antenna apparatus includes a gain setting device for varying gains of AGC of the tuners. Upon searching for the satellite, gains of the tuners are set to a first gain by the gain setting device to perform the rough search and the gains of the tuners are reduced to a second gain level lower than the first gain to perform the fine search. Thus, a time required to catch the satellite after cutting off of radio waves can be reduced.

摘要： A satellite tracking antenna system comprises three or four plane antennas juxtaposed on a single plane. A first and a second antenna are juxtaposed in an azimuth direction, and a phase difference between signals received by these antennas is detected in order to determine a declination of an antenna unit with respect to the satellite as viewed in the azimuth direction. The first and a third antenna are juxtaposed in an elevation direction, and a phase difference between signals received by these antennas is detected to determine a declination of the antenna unit with respect to the satellite as viewed in the elevation direction. The antenna unit is driven so as to reduce these declinations to zero. Stated differently, values of a sine and a cosine function are extracted which have a phase difference between signals received by a pair of antennas as a parameter, and a tangent value representing the ratio therebetween is calculated and is then inversely converted to provide phase difference information.
