A special class of permutation matrices is considered. It is shown that these matrices may be beneficially used to determine the frequency-time pattern of a uniform pulse train. Proper choice ofâ€¦ (More)

A signal bus contains a multiplicity of signals to be recovered. A cooperative arrangement between estimation processors is shown in which each processor acts as an adaptive interference nullingâ€¦ (More)

Beam steering is normally achieved by the use of phase shifters at each element of an array. The phase taper thereby produced causes a shift of the far-field pattern in sin Î¸ space. An alternateâ€¦ (More)

A method for designing high-performance digital filters using only a relatively small number of shift-and-add operations per signal sample is demonstrated.

Use of interpolation processor coefficients as weights in a particular line array format leads to an end-fire pattern having special properties. A wide, nearly constant gain main beam results whichâ€¦ (More)
