Digital Interferometer Direction Finding Technology Based on Bispectrum Phase Detection
摘要
Abstract
In the digital interferometer direction finding system, collecting the phase difference information is influenced by noise, reducing the accuracy of phase detection is based on the bispectrum of Gaussian noi&e is zero, a new phase detection method for digital interferometer direction finding of single frequency signal is presented. On condition of non-noise or Gaussian noise, both of them have the same performance, and the method of collecting the frequency and phase difference information is presented. Compared with traditional phase detection algorithm based on frequency domain, the simulation results show that this algorithm can suppress Gaussian noise and increases the accuracy of phase detection, and the effectiveness of the new method is certified.关键词
