Errors due to random noise in velocity measurement using incoherent-scatter radar

The random-noise errors involved in measuring the Doppler shift of an ‘incoherent-scatter’ spectrum are predicted theoretically for all values of 1 e /1 i from 1.0 to 3.0. After correction has been made for the effects of convolution during transmission and reception and the additional errors introduced by subtracting the average of the background gates, the rms errors can be expressed by a sim...

Robustness of holographic optical traps against phase scaling errors.

Complex three-dimensional patterns of multifunctional optical traps can be encoded in phase-only computer-generated holograms and projected with the holographic optical trapping technique. The trap-forming holograms, in turn, are implemented as diffractive optical elements whose phase transfer functions generally do not faithfully reproduce the design. We demonstrate that phase encoding errors ...

Incoherent Synthetic Aperture Sonar Processing

This chapter investigates the incoherent approach applied in synthetic aperture sonar processing. The details of implementation are shown, and the technical properties of this technique are presented. Simulations are presented along the way for purposes of illustrations and comparisons. Discussions of the potential and limitation of this approach are made. All the simulations and analytical inv...

Fast Reconstruction from Random Incoherent Projections

The Compressed Sensing paradigm consists of recovering signals that can be sparsely represented in a given basis from a small set of projections into random vectors; the problem is typically solved using an adapted Basis Pursuit algorithm. We show that the recovery of the signal is equivalent to determining the sparsest representation of the measurement vector using the dictionary obtained by a...
