超分辨测向中辐射源相关特性研究

Research on the Correlated Peculiarity of Radiation About High Resolution Direction Finding

针对超分辨阵列测向算法中,辐射源模型不是假定为不相关就是假定为完全相关(相干)情况,指出这与实际情况不符,利用理论和仿真实验相结合的方法对影响信号相关性的三个因素(频率、幅度和相位)分别进行了分析。最后给出了产生任意相关度辐射源的方法。

In the arithmetic of high resolution direction finding,the source of radialization is assumed either noncoherent or correlation,but that is not accord with the practice.In this paper we utilize a method of combining the theory with emulation to analyse the three factors(frequency,amplitude and phase)which affect the correlation of the signal.It Rives the way of producing random relativity radiation which offers the good use for reference in the following emulation tests and verifying different kinds of arithmetic.
