Antenna array for aircraft navigation system
专利汇可以提供Antenna array for aircraft navigation system专利检索，专利查询，专利分析的服务。并且An electronically phased control antenna array having a number of radiators which are to be controlled so as to form two beams respectively pointed toward two separate earth satellites in an aeronautical satellite navigation system and wherein the two antenna arrays are controlled through a Butler matrix comprising a distribution network having phase rotation elements and wherein a plurality of outputs which differ in phase are selectively obtained so as to control the direction of the antenna beam, thus maintaining the antenna arrays respectively pointed at the satellites. The selection of the switching control for the matrices which control the antenna arrays may be accomplished by the use of a computer which has a memory for programming the switching in response to a prior flight path over the same region. Alternatively, the outputs from the antenna arrays and matrix may be sampled and the switches of the matrices controlled so as to obtain the largest signal thus assuring that the arrays are pointing toward the satellites.，下面是Antenna array for aircraft navigation system专利的具体信息内容。
