摘要
本文对各种特征结构法的分辨性能作了分析比较,并就信号矢量为复正弦矢量的情形,给出了几种典型的特征结构法对两个等功率非相关信号的信噪比分辨门限表达式。文中还给出了模拟结果,模拟结果与理论分析一致。
The resolution performance for all varieties of eigenstructure ap-proaches is analyzed and compared The formulation results of SNR thresholds to resolve two incorrelated equal power signals for several typical eigensturcture ap-proaches are given. Simulation results are consistent with the theoretical ones.
