Claims20
A method for generating carrier-synchronized signals, said method comprising:
- applying first and second input carrier signals respectively to first and second inputs of a system, the system comprising a first tree network coupled to the first input and a second tree network coupled to the second input, the first tree network having at least one branch, the first and second tree networks having a plurality of internal node pairs, each node pair including a first node on the first tree network and a second node on the second tree network, each node pair being at a different location, and each node pair characterized by a synchronization flight time, and wherein the synchronization flight times of all node pairs of the plurality of internal node pairs are substantially equal;
- and
- for each node pair of the plurality of internal node pairs, processing signals of both the first and second nodes of that node pair to generate a corresponding output carrier signal, wherein for each node pair of the plurality of internal node pairs the carrier phase of the output carrier signal for that node pair is a function of the synchronization flight time for that node pair.
A system for generating carrier-synchronized, said system comprising:
- a first tree network coupled to a first input for receiving a first input carrier signal, the first tree network having at least one branch;
- a second tree network coupled to a second input for receiving a second input carrier signal, the first and second tree networks having a plurality of internal node pairs, each node pair including a first node on the first tree network and a second node on the second tree network, each node pair being at a different location, and each node pair characterized by a synchronization flight time, and wherein the synchronization flight times of all node pairs of the plurality of internal node pairs are substantially equal;
- and
- a plurality of electronic circuits, each for processing signals of both the first and second nodes of a corresponding different node pair of the plurality of internal node pairs to generate a corresponding output carrier signal, wherein for each node pair of the plurality of internal node pairs the carrier phase of the output carrier signal for that node pair is a function of the synchronization flight time for that node pair.
