    • The present invention relates to emitter location. More specifically, it relates to locating emitters using only their fundamental frequency information. The presentinvention recites a method of determining the location of an emitter source comprising the steps of receiving signal information from the source at a plurality of sensors; and simultaneously processing a large bandwidth, and all received signal information using the fundamental RF frequency that lay within the detection bandwidth, and simultaneously determining the relative time of arrival, of all detected signals, using their relative post FFT fundamental detected phases, and using analysis of these relative instantaneous phases to determine all signal source directions within the detected bandwidth. The present invention also recites an apparatus comprising: a first sensor; at least one other sensor located remotely from the first sensor; a central processor connected to the first sensor and each of said other sensors for receiving signal information from each sensor relating to an emitter source and for determining location of emitter sources using their fundamental RF frequency and the technique above.
    • 本发明涉及发射器位置。 更具体地,它涉及仅使用其基频信息来定位发射器。 本发明描述了确定发射源的位置的方法,包括以下步骤:在多个传感器处从源接收信号信息; 并且同时处理大的带宽,并且使用位于检测带宽内的基本RF频率来处理所有接收到的信号信息,并且使用它们的相对后FFT基本检测相位同时确定所有检测到的信号的相对到达时间,并且使用分析 的这些相对瞬时相位来确定检测到的带宽内的所有信号源方向。 本发明还提出一种装置,包括:第一传感器; 位于远离第一传感器的至少一个其它传感器; 连接到第一传感器和每个所述其它传感器的中央处理器,用于接收与发射源相关的每个传感器的信号信息,并且使用其基本RF频率和上述技术来确定发射源的位置。
