This work describes an algorithm called the control circuit encoding (CCE) algorithm that is eec-tive for the remote calibration of an N e element active phased array a n tenna. The algorithm involves transmission of orthogonal encoded signals. CCE is ideally suited for analog beamformers as it requires no additional encoding hardware. The CCE method(More)
The results of a detailed analytical study of the effects of sensor processing techniques on clutter suppression and image enhancement for nondestructive testing (NDT) systems are presented. A relatively simple beamforming/diffraction model is developed for near-field, wideband, synthetic aperture ultrasonic imaging in NDT systems. The physical model is(More)
