摘要

Relative unmanned aerial vehicle attitude is estimated using only on-board radio-frequency signaling. The method uses a direction-ofarrival iDoAl vector estimate to determine two degrees-of-freedom (DoFs), a polarimetric narrowband multiple-input multiple-output NIIMO) channel estimate to specify the third Dot' to within a 1800 ambiguity, and one of the several potential methods for ambiguity resolution. Simulation results demonstrate that the method accurately determines aircraft attitude, with errors proportional to DoA and MINT channel estimate errors. This approach is useful for cooperative navigation when external navigation aids are not available, such as in GPS-denied environments.
