Abstract
An important problem in ultrasonic imaging is target detection under non-ideal imaging conditions. One example of this occurs in nondestructive testing (NDT) where cracks or inclusions must be found in the presence of normal material inhomogeneities (including surface roughness). The material inhomogeneities may create spatial variations in sound speed [1] as well as multi-path pulse distortion and speckle-like “material noise”. Furthermore, the ultrasonic pulse reflected from the target depends on the target shape and composition. Although this work is motivated by problems in NDT, the concept of partially-coherent imaging may also find applications in medical imaging and sonar.
