A New Method of Multi-Component Chirp Signal Array Detection

Abstract:

This paper presents a multi-component chirp signal detection with new methods of parameter estimation. The method using spatial characteristics of the antenna array. By array average fractional Fourier domain weighting function is introduced to reduce noise and suppress mutual interference between the signals from different sources. And compared to a single array element method. The proposed method greatly improves the multi-component chirp signal detection and parameter estimation performance. Simulation results show the effectiveness of the method.
