Weakly interacting massive dark matter (DM) particles are expected toself-annihilate or decay, generating high-energy photons in these processes.This establishes the possibility for indirect detection of DM by \gamma-raytelescopes. For probing the secondary products of DM, accurate knowledge aboutthe DM density distribution in potential astrophysical targets is crucial. Inthis contribution, the prospects for the detection of subhalos in the GalacticDM halo with present and future imaging atmospheric Cherenkov telescopes (IACT)are investigated. The source count distribution and angular power spectra for\gamma-rays originating from annihilating DM in subhalos are calculated fromN-body simulation results. To study the systematic uncertainties coming fromthe modeling of the DM density distribution, parameters describing the\gamma-ray yield from subhalos are varied in 16 benchmark models. We concludethat Galactic subhalos of annihilating DM are probably too faint to be apromising target for IACT observations, even with the prospective CherenkovTelescope Array (CTA).
