Adaptive beamformers are usually based on the premise that noise is stationary and Gaussian, and hence completely characterized by a covariance matrix. The standard approach then attempts to use measured data to estimate that covariance and form a set of beamformer weights that optimally rejects the estimated noise.

A noise impact model (NIM) has been developed that allows the user to examine the impact that quieter aircraft technologies might have on air carrier operating efficiency at major U.S. airports. The analyst selects one of 16 available airports and one of three case years for study, chooses a set of flight tracks, and has the option of reducing the ...

A model of ambient sea noise is developed under the assumption of a surface distribution of noise sources. Volume absorption and the effects of refraction and reflection over long-range paths are included. The derived directional noise field is expressed as a function of vertical arrival angle, with the parameters being velocity profile, surface ...

The Railway Noise Model (RWNM) was developed at the University of Central Florida and predicts sound levels at receivers near railway operations for analyses used in environmental documents. The RWNM is a simulation model, and trains are modeled as moving point sources of sound. The user can create model objects, tracks, barriers, and receivers, using

Polarimetric and interferometric noise modelling
IEEE International Geoscience and Remote Sensing Symposium, 2003In this paper, a noise model for the extended six dimensions covariance matrix used in polarimetric synthetic aperture radar (SAR) interferometry is proposed. This noise model is able to interpret interferometric, as well as polarimetric noise characteristics for the diagonal and non-diagonal elements of the covariance matrix.

An understanding of the origins of noise is required for a receiver's performance to be accurately characterized. The amount of noise present in a receiver will be the primary factor that determines the receiver's sensitivity. In this chapter, we will first review the definitions and analysis techniques needed to understand the effects of noise on a ...
