Method and system permitting the sequential reorganization of signals

Abstract

A method and system for sequentially reorganizing signals received on a set of sensors, including a network of aerials or sensors, a high-precision clock, controlling a sequencer and suitable for accurately pacing the switching and acquisition times between each aerial, the sequencer is suitable for controlling an antenna switch, an the antenna switch linked to a single-channel radiofrequency receive module, an acquisition card, and a processing model.

Description

technical field [0001] In particular, the invention relates to systems and methods for sequentially recombining signals. [0002] The invention is applicable to arbitrary electronic precision and signal processing applications specific to signal acquisition systems (eg, digital receivers). Background technique [0003] In a goniometric environment, the "Sequential Recombination of Signals" function enables the acquisition of the signals received on the antenna network one by one and enables them to be processed as if they were acquired simultaneously. [0004] In goniometric methods, for example, current reception principles are based on the use of analog circuits (hereinafter called hybrids) arranged on the antennas and allow processing operations on signals acquired simultaneously on several antennas. This concept enables the receiver to pick up a combination of antennas, not just one. This principle thus reduces band utilization and is only used for narrowband operating...

AI Technical Summary

Problems solved by technology

The low bandwidth of the hybrid thus means that in order to be able to cover the entire desired frequency band one must have many hybrid phones, resulting in high cost

Another disadvantage of this system is that it is not the signal itself that is digitized, but the function corresponding to the signal that appears on the two antennas

[0006] Systems according to the prior art do not allow access to amplitude information, especially in goniometric methods, where the amplitude information is limited in the algorithm

[0007] Prior art techniques known to the applicant cannot operate over a wide frequency band

They also have no scruples about precise synchronization of signals

Moreover, they do not allow the actual acquisition of the signal, but only the image of the phase ratio of the signal acquired in pairs, which limits the downstream digital processing operations
