Abstract:

This report is concerned with the measurement of frequency Doppler shift by a collection of sensors which may be grouped into two or more clusters subarrays. The signal may be a sinusoid, or it may be a narrowband gaussian process whose center frequency is then the quantity of interest. For much, though not all, of the analysis, it is assumed that the noise is incoherent from sensor to sensor. The signal wavefront is assumed to be perfectly coherent over all sensors, but the angle subtended at the source by the various sensors may be sufficiently large so that differential Doppler shifts cannot be ignored.
