  The prospects of measuring the parameters of WIMP dark matter in a model
independent way at the International Linear Collider are investigated. The
signal under study is direct WIMP pair production with associated initial state
radiation. The analysis is performed in full simulation of the ILD detector
concept. With an integrated luminosity of L = 500 fb-1 and realistic beam
polarizations the helicity structure of the WIMP couplings to electrons can be
determined, and the masses and cross sections can be measured to the percent
level. The systematic uncertainties are dominated by the polarization
measurement and the luminosity spectrum.
