Extract

The use of the theory of geometrical acoustics in the calculation of focussed bangs has received wide attention over the past two decades. None of these calculations however had been formulated for an aircraft manoeuvring in an arbitrary manner in a real atmosphere. Further, in most cases the results have not been presented in such a manner as to be useful to practising engineers. Recent formulation now permits the prediction of the focussing ray precisely and directly without having to compute all the rays reaching the ground from the source.
