  A theoretical model based on two-point scatterers is suggested to investigate
scattering of partially coherent radiation by a non-Hermitian localized
structure, invariant under the simultaneous symmetry operations of parity
inversion and time reversal. Within the first-order Born approximation, and the
formalism of classical coherence theory, the spectral density of the scattered
field in the far zone is obtained analytically. We find that the unidirectional
character of the scattered radiation, which is one of the principal effects
present in non-Hermitian structures, may be suppressed due to the coherence
properties of the radiation without changing the geometry of the structure.
Asymmetric spectral changes of the scattered radiation due to the non-Hermitian
character of the material are also observed.
