Title: 未知信号のソースを特定するための方法および装置
IPC: H04B7/185
Filed: 2002-03-18
Abstract: 中継衛星１２、１４を介して、受信アンテナ１６、１８によって受信された変動する周波数の未知信号のソースを特定する方法には、受信信号を第１中間周波数ＩＦにダウンコンバートし、ダウンコンバートした信号を帯域制限することが含まれる。帯域制限された信号は、未知信号の周波数変化を抑制するために、局部発振器ＬＯのダウンコンバート周波数を調節することによって、事前に構成した獲得信号帯域幅内にあるように制約される。ダウンコンバートした信号は、差分時間オフセットの試行値を使用して、互いに、時間についてオフセットされ、それらの相関は、実際の時間オフセットを提供するように、各試行値に対して決定される。相関位相角の変化に対して、補償が提供され、この補償は、試行オフセットの時間間隔中に、異なるＬＯ周波数を経験する、ダウンコンバートされている信号から得られる。
