The initial radius effect is one of the major obstacles to well-calibrated fluxes from meteor radars. This effect is dependent on the wavelength of the radar used, and will be affected by the dependence of initial radius on height and the density profile of electrons in the ionized trail. Most previous studies have assumed a Gaussian profile of electrons in the trail, and have found from multifrequency studies that the initial radius varies more slowly than the mean free path with height. Studies of meteors in the size range similar to that detected by most radars show that they are not single bodies, but fragment prior to luminous ablation; fragmentation is potentially a very significant effect in the initial radius correction. We present a study of the effects of fragmentation on initial radius using a combination of numerical simulation and data from a multifrequency radar.
