接收阵列天线的时-空二维谱估计

Spatio-temporal Spectral Estimation of Received Array

该文对二维信号应用空间平滑技术进行谱估计 ,解决相干信号源的频率—方位超分辨估计问题。将该方法应用于车载雷达自动目标识别系统中 ,仿真结果表明 。

Spatial smoothing technology was applied to estimate spectrum of 2-dimensional signals.The technology can slove the problem of the super-resolution in frequency-bearing domain of coherent signals.The method is applied in automatic target identification radar system equipped on vehicle and the simulated results prove its practice and effectiveness.
