It is shown that for a broad class of random binary processes, the mean of a binary process, conditioned on its zero crossings, is proportional to the derivative of the correlation function of that process. This specific mean, referred to as the impl

Simulations have been carried out to determine suitable sensor arrangements for use in cross-correlation flow measurement of pulverized coal using electrostatic sensors. A system using complementary Golay codes allows the sidelobes on the correlation

A novel ion beam profiler has been developed for measuring a two-dimensional current distribution of an ion beam. The system consists of two parallel disks rotating at different speeds and mounted in front of a single Faraday cup. The cup intercepts

A method is presented to measure the position of an ion beam centroid. The method uses two precise nonlinear slits located in the plane of a spinning disk and a stationary Faraday cup mounted behind the disk. A beam centroid position is converted int

Discrete-time samples of isotropic clutter with symmetric alpha-stable (S/spl alpha/S) distribution are generated by modulating a complex correlated Gaussian sequence with a nonnegative sequence with skewed stable distribution. The quadrature compone

A new method is proposed to generate a discrete-time correlated Laplacian process from four mutually independent, discrete-time Gaussian processes with suitably chosen correlation functions. In contrast to some other known methods, the entire range o

A fast time-domain technique is proposed to estimate the root mean square (rms) bandwidth of a Gaussian random process. The method is based on averaging the absolute values of the derivative of a signal at zero crossings. For processes with Gaussian

It is shown that each quadrature component of K-distributed clutter with shape parameter V/spl ges/1/2 can be modelled, exactly or approximately, by a weighted sum of products of two independent Gaussian variables. The normalised autocorrelation func

A novel method is presented for estimating a normalised correlation function from discrete-time observations. The performance of the method approaches that of a maximum likelihood estimator. Because multiplication and division are replaced by logarit

A solution is offered to the problem of estimating a beam parameter from random signals induced by a continuous ion beam on sensing electrodes. Two models for such signals are proposed: one is based on a homogeneous Poisson point process, whereas the
