Abstract :
In order to monitor the interference in GNSS, the bearings measurement of the interference source is needed. Because the high-order cumulant (HOC) is able to suppress Gaussian nose, a music algorithm based on the Interference Bearings Measurement 4-order cumulant of circle array GNSS is put forward. The MUSIC algorithm based on HOC can be used in GNSS Interference Bearings Measurement to decrease the demand of SINR in measurement. The experiments under the condition of Gassion noise show that, the MUSIC Algorithm based on HOC has better robustness and accuracy than MUSIC.
