AI Technical Summary

Technical Problem

In the case of high dynamics of distributed nodes, it is difficult for the prior art to obtain the position information of the transmitting nodes in real time, resulting in the inability to accurately estimate the phase difference between each transmitting node, which in turn causes serious gain loss in the synthetic gain of the distributed transmitting phase-conference system.

Method used

Through a distributed high dynamic node system, including a distributed node signal transmission model construction module, a variable frequency module, a filter module, a parameter estimation module and a performance evaluation module, real-time estimation and pre-compensation of phase difference between transmit nodes is realized to maximize the phase comparison synthesis gain of distributed nodes.

Benefits of technology

Real-time phase difference estimation and pre-compensation in the case of high dynamic nodes is realized, which maximizes the distributed transmission phase comparison synthesis gain, and improves the flexibility and real-time nature of the system.

Abstract

The invention discloses a distributed high-dynamic node system and a transmitting beam coherent synthesis method thereof, and belongs to the technical field of antennae, and the method comprises the following steps: firstly, enabling and resetting N transmitting nodes to keep signal synchronization, and providing two working modes of single transmitting and simultaneous transmitting of a modulation signal and a positive / negative single-tone signal, the N nodes transmit wireless signals after keeping signal carrier homology; respectively carrying out down-conversion and low-pass filtering on the received modulation signal or multi-tone signal at a receiving node; secondly, estimating the phase difference between the transmitting nodes according to the positive / negative single-tone signals transmitted by the N nodes; and finally, feeding back a phase difference result to the transmitting node for pre-compensation, and maximizing the transmission participation synthetic gain of the distributed nodes. The method has the advantages of being flexible in expansion, high in real-time performance and easy to implement.
