The large bandwidth and large antenna arrays of millimeter-wave (mm-wave) systems make them an interesting technology for integrated communication and sensing, where communication hardware and waveforms are re-used for sensing applications. Existing multipath component (MPC) estimation algorithms are designed for multi-antenna systems which rely on digital beamforming, where the baseband signal of each antenna is easily accessible at the receiver. In this paper, we propose a MPC estimation algorithm tailored to typical and cost-effective mm-wave system hardware, which typically relies on analog beamforming. The proposed MPC estimation algorithm does not suffer from the presence of an antenna array sidelobes, unlike classical angular power profile estimation algorithms. The algorithm's performance is evaluated through simulations, and is validated on a 28 GHz experimental testbed. The results show that our algorithm is effectively able to identify individual MPC contributions, without suffering from the influence of antenna array sidelobes.
