Monte Carlo Simulation of Altimeter Pulse Returns and Electromagnetic Bias

IGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008
The electromagnetic bias is a critical error term in sea surface height estimation from satellite radar altimetry. While the electromagnetic bias has been studied extensively, most studies are based on low-order hydrodynamic and electromagnetic models. This paper proposes an alternate approach for electromagnetic bias studies by employing a Monte Carlo

Study on the electromagnetic influence of DC bias on the power transformer

2009 IEEE International Symposium on Electromagnetic Compatibility, 2009
DC bias of transformers will generate some important effects on power transformers. Furthermore it can bring about a malfunction of the power system. A simulation model is set up and the equivalent coupled electric circuit and magnetic circuit method is used to analyze the electromagnetic influence of DC bias.

A laboratory study of the electromagnetic bias of rough surface scattering by water waves

IEEE Transactions on Geoscience and Remote Sensing, 1990
The design, development, and use of a focused-beam radar to measure the electromagnetic bias introduced by the scattering of radar waves by a roughened water surface are discussed. The bias measurements were made over wide ranges of environmental conditions in a wavetank laboratory.

Non-linear waves and the electromagnetic bias

IGARSS '98. Sensing and Managing the Environment. 1998 IEEE International Geoscience and Remote Sensing. Symposium Proceedings. (Cat. No.98CH36174), 1998
The theory of 'weakly' nonlinear (WNL) waves is commonly used in generating higher statistical moments of a random surface wave field. These moments can be used, for example, to estimate the sea state bias (SSB) in radar altimetry under a geometric optical (GO) assumption.

Measurements of electromagnetic bias in radar altimetry

Journal of Geophysical Research: Oceans, 1991
The accuracy of satellite altimetric measurements of sea level is limited in part by the influence of ocean waves on the altimeter signal reflected from the sea surface. The difference between the mean reflecting surface and mean sea level is the electromagnetic bias.

Short waves in the electromagnetic bias theories

IEEE 1999 International Geoscience and Remote Sensing Symposium. IGARSS'99 (Cat. No.99CH36293), 2003
Most previous theories on the altimeter electromagnetic bias (EM-bias) have focused on long waves and their influence through high-order surface statistics. A modification is presented based on the two-scale philosophy where short waves are tilted and modulated by longer ones. Short waves are found to have an essential effect on the EM-bias revealed in

An improved model for determining the electromagnetic bias

IGARSS 2000. IEEE 2000 International Geoscience and Remote Sensing Symposium. Taking the Pulse of the Planet: The Role of Remote Sensing in Managing the Environment. Proceedings (Cat. No.00CH37120), 2002
Recent experiments have shown fundamental differences id the electromagnetic (EM) bias between different regions of the world. In order to account for these difference, various sea and weather parameters are analyzed. A new parameter called wave slope is derived.
