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.

Claims

1. A system for sequentially reorganizing signals received on a set of sensors, comprising:

a plurality of sensors;

a sensor switch having a plurality of sensor ports, a control port and an output port, the sensor switch configured to switch the output port to one of the sensor ports, wherein the sensor port is in communication with a sensor;

a sequencer in communication with the control port, the sequencer configured to control the switching of the sensor switch;

a clock for clocking the sequencer, the clock suitable for pacing switching and acquisition times of the sequencer;

an acquisition card in communication with the output port of the sensor switch; and

a processing module in communication with the acquisition card.

2. The system as claimed in claim 1, wherein the sensor switch is an N to 1 receive channel switch.

3. The system as claimed in claim 1, further comprising a formatting module for formatting the signal between the sensor switch and the acquisition card.

4. The system as claimed in claim 3, wherein the formatting module is a single-channel radiofrequency receive module.

5. The system as claimed in claim 1, further comprising a goniometry module.

6. A method for sequentially reorganizing signals received on a plurality of sensors, comprising the steps of:

repeating, for at least a predetermined portion of the plurality of sensors, the steps of;

acquiring a first signal received by a predetermined sensor, to produce a first acquired signal of the predetermined sensor;

storing the acquired signal, to produce a first stored signal of the predetermined sensor; and

switching to another predetermined sensor of the predetermined portion of the plurality of sensors;

performing, for a selected sensor of the predetermined portion of the plurality of sensors, the steps of;

acquiring a second signal received by the selected sensor, to produce a second acquired signal of the selected sensor; and

storing the second acquired signal, to produce a second stored signal of the selected sensor;

comparing, for the selected sensor, the first acquired signal to the second acquired signal, to produce an existing switching error;

applying the existing switching error as an error correction to each of the first stored signals; and

correcting a phase error due to a switching time.

7. The method as claimed in claim 6, wherein the selected sensor is the first sensor.

8. The method as claimed in claim 6, further comprising a goniometry step.

9. The method as claimed in claim 7, further comprising a goniometry step.
