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)
Tripulse is a novel orientationnattitude estimation system that is designed to accurately estimate the orientation of a satellite borne phased array relative t o one or more earth stations. This system has an accuracy potential that is signiicantly better than conventional Earth-Moon-Sun attitude sensors. Tripulse has conceptual similarities to amplitude(More)
