Abstract :
The airspeed measurement problem based on a vector sensor array is researched in this paper. According to the propagation principle of acoustic wave in air, the measurement model of wave´s particle velocity based on an acoustic vector array is set. Then a direct airspeed estimation algorithm is proposed. The proposed algorithm does not need matrix decomposition and has a good real-time performance. Finally, the suppression of perturbation is analyzed. Simulation results show the effectiveness of the proposed algorithm.
