The Detection of the Electromagnetic Sinusoidal Burst in the Presence of Correlated Noise

Abstract The polarity coincidence correlation detector is analysed for the detection of electromagnetic sinusoidal burst of nearly known frequency in the presence of correlated noise. The source is assumed to be buried several hundred meters deep in the ground. Polarity coincidence and two polarity difference statistics (caused by introducing shifts of ±180° in a channel) are presented for various noise models. The degradation caused by various uncertainties in the signal parameters are also discussed and methods are presented to overcome them.
