Abstract

The radio emission from air showers is used to accurately reconstruct the depth of the shower maximum (Xmax). We present a method based on using the full two-dimensional radiation profile as observed on the ground. While the density of shower particles reaching the ground is usually described with a 1D lateral distribution function, the intensity of the radio pulse is a complex function of observer position with respect to the shower axis. The CoREAS code simulates these complicated patterns to very high precision. When the antenna density is sufficiently high, like for example in the LOFAR core, the 2D approach leads to a resolution on Xmax of < 20 g/cm2. This is the same level of accuracy that is achieved with fluorescence detection.
