Numerical simulation of backscatter from linear and nonlinear ocean surface realizations
- C. Rino, T. L. Crystal, Alan K. Koide, H. D. Ngo, H. Guthart
- Physics
- 1991
In this paper, numerical simulations of the scattering from time-dependent realizations of one-dimensional ocean surface waves are described. A new technique is used that allows efficient generation… Expand
Velocity effects in synthetic apertures
- K. Graf, H. Guthart
- Physics
- 1 September 1969
An antenna capable of high resolution can be synthesized by moving a side-looking radar a long distance and treating positions along the path as the positions of elements in an actual physical array.… Expand
Correlation techniques and measurements of wave-height statistics
- H. Guthart, W. Taylor, K. Graf, D. Douglas
- Physics
- 1 December 1972
Statistical measurements of wave height fluctuations have been made in a wind wave tank. The power spectral density function of temporal wave height fluctuations evidenced second-harmonic components… Expand

Electromagnetic emissions in vicinity of proton gyrofrequency from OGO 2 satellite measurements, noting sweep frequency receiver PCM and Rayspan special purpose data
The Use of Ion Probes in Re-Entry Physics
- H. R. Bredfeldt, W. Scharfman, H. Guthart, T. Morita
- Physics
- 1 May 1965
Abstract : Classical (Langmuir) probe theory is reviewed and the conditions under which it is applicable to the re-entry physics problem identified. Some later developments in probe theory, which… Expand

Boundary-Layer Ion Density Profiles As Measured by
- H. R. Bredfeldt, W. Scharfman, H. Guthart, T. Morita
- Materials Science, Chemistry
- 2 March 1966
Ion-density profiles in boundary layers associated with supersonic flow of shock-heated air over a flat plate have been measured by cylindrical and flush-mounted electrostatic probes. A method of… Expand
Microwave Scattering From an Underdense Turbulent Plasma
- H. Guthart, D. Weissman, T. Morita
- Physics
- 1 November 1966
The bistatic radar cross section of an underdense, inhomogeneous turbulent plasma was measured at X-band and the results were compared with a theoretical model. The turbulent plasma was formed by… Expand
A High-Power S-Band Filter (Correspondence)
- H. Guthart
- Mathematics
- 1 March 1962
This note describes the measured performance of a high-power S-band "waffleiron" filter. Techniques for designing varying-impedance corrugated waveguide filters in rectangular waveguide have been… Expand
Measurements of the Charged Particles of an Equilibrium Turbulent Plasma
- H. Guthart, D. Weissman, T. Morita
- Physics
- 1 September 1966
