The hybrid Fourier transform, involving a linear combination of the cosine and sine functions as its kernel, is generalised for discontinuous but integrable functions, in the half-range comprising of the positive real axis. The present generalisation of the hybrid transform is observed to be useful in the area of two-dimensional wave problems involving a two-fluid region as opposed to the well-known hybrid transform, known as Havelock's expansion theorem, whose use is limited to the study of water wave problems involving only a single fluid medium.
