Simultaneous multi-channel ultrasound detection via phase modulated pulse interferometry

Computational Burden in Moving Target Detection in Multi-Channel SAR using Phase Interferometry

The authors have shown in several earlier papers that large ground moving targets can be detected fairly reliably via phase-interferometry in multi-channel Synthetic Aperture Radar (SAR) images of the ground. In a interferometric phase image, all points on the ground nominally appear as a continuum of phase differences while the moving targets appear as discontinuities. By detecting these anoma...

Parallel detection of amplitude-modulated, ultrasound-modulated optical signals.

We investigated the effect of amplitude-modulated (AM) ultrasound (US) on acousto-optic (AO) signals. A phantom was exposed to both AM US and a green laser, and CCD measurements of speckle contrast were made with various exposure times. The results show that the AO signal oscillates at the AM frequency when the CCD exposure time is a fraction of the AM period and stops oscillating when the CCD ...

Channel Estimation and Signal Detection of Pulse Code Modulated Optical Scattering Communication

For developing the receiver side digital signal processing techniques, necessary for the non-line of sight (NLOS) optical wireless scattering communication channel model. A linear time-invariant (LTI) Poisson channel modeling method, to model the NLOS optical wireless scattering communication, which was originally proposed for molecular communication is considered. In such a model the stochasti...
