Spectrum sensing with helicopters in very low altitude area

In this paper, based on the analysis of the complicated electromagnetic environment in very low altitude area, we propose a helicopter spectrum sensing scheme by integrating the energy detection and the cyclostationary feature detection methods. The proposed scheme is able to satisfy the real-time and high accuracy requirements imposed by implementing spectrum sensing with helicopters. Simulations and experiments with collected data in high frequency band verify that the proposed helicopter spectrum sensing scheme is with good performance is feasible for practice use. Moreover, the proposed scheme can choose suitable communication frequencies for helicopters and enhance the communication assurance capability in low altitude area.
