This paper is devoted to the problem of channelled ultrarelativistic positron radiation in the longitudinal standing hypersonic (HS) wave field. Analytical expressions for the first harmonic radiation intensity and for the upper limit of the radiation frequency depending on the HS wave parameters are obtained in the case of planar channelling. The radiation is shown to acquire a dispersive character depending on the HS wave frequency.
