Synthetic Aperture Radar (SAR) image formation using an L1 norm minimization approach is discussed. The use of algorithms such as the Polar Format Algorithm with L1 norm minimization combines the advantages of a far field scattering assumption with t

The numerical solution of a non-linear wave equation can be obtained by using spectral methods to resolve the unknown in space and the standard Crank-Nicolson differencing scheme to advance the solution in time. We have analyzed iterative techniques

Spherical implosion experiments have been performed using shaped laser pulses at ${\ensuremath{\lambda}}_{0}$=0.53 \ensuremath{\mu}m to illuminate deuterium-filled polyvinyl alcohol (PVA) spherical shells. The deuterium fuel was cryogenically cooled

ABSTRACT The radiation of a large amplitude ion-acoustic wave launched from a conical antenna is experimentally measured and contrasted with linear radiation. Significant differences are observed.

A mechanism for the excitation of linear and nonlinear ion-acoustic waves in a double plasma machine is suggested. A compressive ion density perturbation is interpreted in terms of 'klystron bunching' and a refractive ion density perturbation is inte

For pt.II see ibid., vol.26, no.6, p.799 (1984). The authors extent their study on grid excited ion-acoustic solitons to examine far field radiation characteristics. In particular, for propagation distances greater than any launching grid dimension,

The diffraction of planar ion–acoustic waves, both linear and nonlinear by a single rectangular aperture has been investigated. The results of an experiment conducted in a double plasma device have been compared with the predictions of an applicati

Low-frequency noise (fci < f < fpi) excited by positively biased probes of various diameters near the magnets in a multidipole plasma device is investigated. It is concluded that the noise is due to the excitation of oblique ion-acoustic waves, i.e.,

The resonant interaction of two spherical ion-acoustic solitons is observed. A new soliton whose amplitude is approximately three times the colliding soliton's amplitude is created. The spatial growth and decay of the enhancement is noted.
