Detection of Defective Sensors from Compressed Measurement Using Orthogonal Matching Pursuit
In this paper, a greedy algorithm called Orthogonal Matching Pursuit (OMP) can reliably diagnose faulty sensors in array antenna from compressed measurements. This technique starts from collecting the measurements of the far-field pattern generated by the array under test. The difference between the measured healthy reference array pattern and collected measurement is minimized using a greedy algorithm. The simulation results based on OMP validate the detection of faulty sensors from compressed number of measurements.
