Coherent effects in the radiation from finite-sized nonuniform particle beams penetrating the ionosphere are studied. For illustrative purposes, special beam structures are assumed which permit the coherent radiation effects to be extracted from the complicated integrals of the more general theory as an explicit analytic factor. The results are used to show a possible mechanism for generation of narrow-band low-frequency noise peaks.
