The detection of fully and partially defective sensors in a linear array composed of Nsensors is addressed. First, the symmetrical structure of a linear array is proposed. Second, a hybrid technique based on the cultural algorithm with differential evolution is developed. The symmetrical structure has two advantages: (1) Instead of finding all damaged pattes, only (N–1)/2 pattes are needed; (2) We are required to scan the region from 0° to 90° instead of from 0°to 180°. Obviously, the computational complexity can be reduced. Monte Carlo simulations were carried out to validate the performance of the proposed scheme, compared with existing methods in terms of computational time and mean square error.
