Definitions
- the present invention provides a system and method for sequentially rearranging signals.
- the invention is applicable in any electronic application of precision and signal processing dedicated to signal acquisition systems (for example digital receivers).
- the current reception principle is based on the use of analog circuits (called hybrids thereafter), placed at the level of the aerial, and allowing processing on signals acquired at the same time on several air.
- This concept allows the receiver to acquire a combination of aerial but not a single aerial. This principle therefore reduces the band of use and is reserved for systems operating in narrow band, less than one octave.
- Prior art techniques known to the applicant do not allow to operate over a wide frequency band. They also do not allow precise synchronization of the signals. In addition, they do not allow the actual acquisition of signals, but only the acquisition of the image of the phase ratio of signals taken two by two, which limits digital processing downstream.
- the invention relates to a system for sequentially rearranging signals received on a set of sensors, characterized in that it comprises in combination at least the following elements:
- the sequencer is adapted to control a sensor switch
- the invention also relates to a method for sequentially rearranging signals received on a set of sensors, characterized in that it comprises at least the following steps:
- o acquire a signal received on a sensor of the set, store it, then switch to acquire another signal received on another sensor of the set, o reiterate the acquisition of the signals received on each of the sensors of the assembly until all or most of the sensors have been scanned, and store all the acquired information, o select one of the sensors on which the signal has previously acquired and reiterate a signal acquisition and storage cycle for this reference signal, o compare this acquisition with the acquisition previously obtained for the same sensor, o determine from this comparison the existing switching error, o apply the error correction to each of the recorded signals, o correct the phase error due to the switching time.
- the object of the invention has notably the advantages of eliminating the hybrid components of the systems according to the prior art and sequentially acquiring the signals on each aerial while controlling the phase errors.
- the figure represents a system structure comprising for example:
- a network of 1 n air or sensors o a high precision clock 2, controlling a sequencer 3 and for accurately timing the switching and acquisition times between each air 1 n, o the sequencer 3 itself controls a antenna switch 4, for receiving signals, the antenna switch 4 is connected to a single-channel radiofrequency reception module 5, an acquisition card 6, and a processing model 7.
- the antenna switch 4 is particularly adapted and selected to perform the passage from one air to another.
- the antenna switch 4 is for example an N switch overhead to 1 receive channel.
- the function of the antenna switch 4 is notably to let the signals of an aerial pass to the devices situated in the processing chain and to block the signals coming from the other aircrafts. It has particular particularity of having an identical or substantially identical opening / closing response time on each of the air routes.
- Sequencer 3 generates the management function of the switch. Its particular function is to select the channel that is connected to the desired air.
- Clock 2 is used to clock the sequencer.
- the scanning cycle of all the airs is chosen so that the frequency of the clock is stable.
- the order of magnitude is for example 10 "10 .
- the RF device 5 is a radio reception module. This module has the particular function of transposing the reception frequency band to an intermediate frequency which is returned to the acquisition card 6.
- the acquisition card is adapted in particular to quantify the signals received on each aerial and to send them to the processing module 7.
- the system implements a goniometry algorithm appropriate to the antennal system.
- the structure functions for example as described below.
- the idea is based in particular on a sequential acquisition of the signals on each aerial, and their temporal coherence while controlling the phase errors.
- Each aerial is connected to an N-to-1 antenna switch that is controlled by the sequencer clocked at a clock speed
- a signal is then selected from among those that have been acquired, then an N + 1 switching is performed, that is to say for example on the first air and the acquisition is redone.
- This last acquisition is compared to the first acquisition. This comparison makes it possible to determine an existing error and to reset each of the acquisitions. Since the signal is considered stationary or substantially stationary during a signal acquisition cycle (acquisition over a very short period of time), it is able to estimate its value with respect to that acquired and therefore to deduce the drift that n is other than switching errors.
- the system can: o Firstly, correct the overall error on each recorded signal, and o then correct the phase error due to the switching time,
- the system is clocked at the rhythm of the sequencer with the accuracy of the clock.
- the sequencer controls the switch.
- the system and the method according to the invention apply for any measurement chain which implement a parallel acquisition of signals.
