FM band commensal radar technology used for the detection of small aircraft and the measurement of propeller modulation

摘要

Commensal radars (CR) depend on transmitters of opportunity whilst having no impact on the systems the transmitters are serving. This paper presents initial trials conducted to investigate the performance of an FM radio band based CR system against smaller aircraft. We present the detection range results and also demonstrate that we could accurately determine the rotation rate of the aircraft's propeller.
