Abstract

The LFM signal is commonly used in both radar and sonar system. However, the steering vector of the LFM signal is changed with time, traditional DOA ectimation method cannot be used. A DOA estimation method of fourth-order cumulants based on fractional Fourier transform is proposed in this paper. By this method, the uses of popular DOA estimation algorithms are extended to LFM signal. Simulation results show that the method proposed can be used both in single and multi- sources.
