title = "Detection of specular reflectors and suppression of speckle by phase filtering",
abstract = "The object detection capabilities of ultrasonic imaging systems are limited by the ability of the detection process to distinguish resolved object signals from backscattered speckle noise. It has been shown that the phase of the Fourier transform of speckle signals is random. Based on this property, the authors propose a novel algorithm for distinguishing between speckle and specular targets. The proposed algorithm is implemented by taking the Fourier transform of the received signal, low-pass filtering the unwrapped phase, and taking the inverse Fourier transform of the filtered phase to produce a specular reflector enhanced and speckle reduced ultrasonic image. The algorithm has been confirmed by simulations and experiments using phantoms.",
