[C1] Auto-Calibration

General Aim: This project is concerned with signal processing techniques for on-line calibration and recalibration of sensor arrays in order to compensate errors/uncertainties in location (geometrical errors), phase and gain (electrical errors), synchronisation, etc, even when all errors/uncertainties are present simultaneously and can change with time.

Array of sensors: An "uncalibrated" array of N sensors of arbitrary geometry will be considered operating in a multitarget environment where the array uncertainties/errors can degrade signi…cantly the array performance either slowly or even abruptly. Note that the array input vector-signal may contain also sperious signals due to sensor/hardware problems while sensor failure (partial or full), will be studied as part of the array calibration problem.

In summary, in this project the problem of uncertainties/errors in sensor-arrays will be addressed using "hybrid" auto-calibration approaches. This is a mixture of novel pilot and self calibration techniquescombined in an smart and automated way. The proposed algorithms will be veri…ed using Imperial College hardware platform.
