Abstract : The ideas of Atlas and Wexler on wind measurement using a dual-beam incoherent radar have been extended. An alternate theory for this measurement technique is presented. It is shown that the normalized Doppler spectrum can be obtained by convolving the normalized contamination spectrum (shifted by the radial component of the wind) with the normalized antenna pattern (stretched by the tangential component of the wind). This approach allows the following generalizations from the theory of Atlas and Wexler: The two beams need not be identical in shape and peak gain; The individual antenna patterns need not be Gaussian; The angle between the beams may be large; The volumes observed by the two beams need not have equal reflectivity and equal contamination variance.
