摘要 演化谱估计作为研究非平稳信号的重要手段,具有许多优良的性质。将演化谱应用于参数估计和宽带阵列信号处理中,提出了RadonEP(EvolutionaryPeriodogram)谱变换(REPT)估计线性调频信号参数和空间分段短时EP谱估计宽带线性调频信号到达角。仿真实验显示了算法的有效性。 As an important tool to analyze non-stationary signals, the evolutionary spectrum has many good properties. Aiming at the application of evolutionary spectrum in parameter estimation and array signal processing, the Radon-EP and spatial section short EP transform is presented to estimate the frequency and spatial parameter of wideband Linear Frequency Modulated （LFM） signals in this paper. The simulation results show efficacy of the proposed methods.
