摘要
应用二维傅立叶变换的时空谱估计技术研究了测向问题,给出了基于正弦相参信号时空谱的测向理论表达式,并详细分析、评估了本测向方法的性能。最后,通过计算机仿真实验验证了本测向算法的有效性及可行性。
A new approach of DF （direction finding） based on two dimensions Fourier transform spatio-temporal spectral estimation technology is studied. The spatio-temporal spectral estimation theory expression based on sine coherent signal is proposed. DF performance of this method is analyzed particularly. To validate the theory, computer simulation is offered, and the study shows that the proposed method is efficient and practical.
