We present an approach to high-resolution direction-of-arrival estimation for distributed radar sensors without the need for synchronization or wired connections. The sensor signals are post-processed and combined after range-Doppler processing achieving a larger virtual aperture and multiple snapshots. The proposed approach is validated via simulations and the effectiveness is compared to other baseline estimators with respect to estimation accuracy and resolution performance. Finally, the applicability on real data is demonstrated using a simple measurement setup in an anechoic chamber.
