For stationary random data, an automatic estimation algorithm can now select a time series model with a spectral accuracy close to the Cramer-Rao lower bound. The parameters of that selected time series model accurately represent the spectral density and the autocovariance function of the data. That is all the possible information for Gaussian data, as well as the most important information for ar... View full abstract»

Two complementary numerically efficient frequency-domain methods for locating stray-signal sources in anechoic chambers are investigated and applied in combination to actual measurement data. Both methods use single-frequency near-field data collected on a planar surface and process them to reconstruct field values (images) elsewhere. The first method, which is based on the fact that the probe out... View full abstract»

In this paper, the constant false alarm rate (CFAR) detectors are proposed for network intrusion detection. By using an autoregressive system to model the network traffic, predictor error is shown to closely follow a Gaussian distribution. CFAR detector approaches are then developed on the prediction error distribution. In the present study, we consider the optimal CFAR, the cell-averaging CFAR, a... View full abstract»

The dynamic range of a spectrum monitor can be extended by incoherently averaging the difference between the spectrum from the antenna and the spectrum from a comparison load. We show that it is often advantageous to increase the attenuation to the spectrum analyzer, thereby lowering the maximum signal strength at the mixer and subsequently compensating for the added noise by incoherent spectral a...
