LOPES was the radio extension of the KASCADE-Grande particle-detector arrayconsisting of up to 30 antennas measuring the radio emission of cosmic-ray airshowers between 40 and 80 MHz with an energy threshold of around 100 PeV. Evenwith the external trigger by the particle detectors, the separation of theair-shower signal from the radio background was difficult in the noisyenvironment of the Karlsruhe Institute of Technology. For the typical eventthis was only possible because of the digital, interferometric beamformingtechnique pioneered by LOPES for cosmic-ray detection. Using this techniqueLOPES made important discoveries with respect to the radio emission of airshowers and their relation to the shower properties, such as its energy and itslongitudinal development. By now, practically all results have been confirmedby subsequent antenna arrays, but regarding digital interferometry the LOPESresults are still unique. Lately we completed an end-to-end pipeline for CoREASsimulations of the radio emission including measured background and all knowndetector responses as well as the interferometric analysis technique. As resultwe present an update on the reconstruction of the most important showerparameters: arrival direction, energy, and $X_\mathrm{max}$.
