Abstract

Formulas for the pseudoinverse of a compact operator are applied to linear system identification and scattering function estimation from a finite set of noisy measurements. The result is a nonparametric estimator possessing several desirable features. The approach encompasses the Modified Discrete Fourier Transform and is applied herein to the important problem of closely spaced object resolsution in radar/optical signal processing.
具有离散测量的连续线性系统的非参数辨识
将紧算子的伪逆公式应用于线性系统辨识和有限噪声测量的散射函数估计。结果得到一个具有若干理想特征的非参数估计量。该方法包含了改进的离散傅里叶变换,并在此应用于雷达/光学信号处理中的近间隔目标分辨率问题。
