Low rank detectors for Gaussian random vectors

IEEE Transactions on Acoustics, Speech, and Signal Processing, 1987
A constructive procedure is presented for designing low rank detectors which maximize the divergence between hypotheses about the covariance structure of Gaussian signals. The detectors are constructed from the eigenstructure of a "signal-to-noise ratio" matrix.

On Four Suboptimal Quadratic Detectors for Random Signals

IEICE Transactions on Communications, 2005
This paper tackles the problem of detecting a random signal embedded in additive white noise. Although the likelihood ratio test (LRT) is the well-known optimum detector for this problem, it may not be easily realized in applications such as radar, sonar, seismic, digital communications, speech analysis and automatic fault detection in machinery, for ...

Signal detectors for random ocean media

The Journal of the Acoustical Society of America, 1992
This paper reports on acoustic signal detection in a stationary random multipath environment. The multipath transmission channel is modeled considering that both multipath time delay and attenuation coefficients characterizing the emitter/receiver transfer function are random variables with an a priori given distribution. Under the above condition, and

Array Detectors for Random Signals in Noise

IEEE Transactions on Sonics and Ultrasonics, 1976
Two schemes for the detection of a common random signal in an array of receivers with independent noise processes are considered. A nonparametric array detector using the Wilcoxon signed-rank statistic and a robust array detector extendingthe binary quantization of polarity coincidence arrays are described and analyzed for performance.
