  We construct special cycles on the moduli stack of unitary shtukas. We prove
an identity between (1) the r-th central derivative of non-singular Fourier
coefficients of a normalized Siegel--Eisenstein series, and (2) the degree of
special cycles of "virtual dimension 0" on the moduli stack of unitary shtukas
with r legs. This may be viewed as a function-field analogue of the
Kudla-Rapoport Conjecture, that has the additional feature of encompassing all
higher derivatives of the Eisenstein series.
