The problem of electromagnetic emission of an edge dislocation segment moving in an ionic lattice with a NaCl-type structure was considered. The proposed mechanism of electromagnetic emission was associated with the appearance of macroscopic alternating polarization currents along the extra-plane edge of the edge dislocation in the course of its motion between adjacent valleys of the Peierls relief. The relationships for electromagnetic radiation fields of an arbitrarily moving segment were derived, and the problem of electromagnetic emission of a segment that executes harmonic oscillations in the field of an external quasi-stationary elastic wave with a frequency much less than c/l (where l was the segment length and c was the velocity of sound) was treated in detail. The power of the emitted electromagnetic signal and the so-called acousto-electromagnetic transformation coefficient (the ratio between the electromagnetic
radiation power and the mechanical power required for setting the segment in motion) were determined.
