Method and apparatus for a tunable high-resolution spectral estimator |
摘要 |
A high resolution spectral estimator (HREE) filter coupled to a spectral plotter processes either Doppler frequencies provided from the output of a pulse-Doppler radar or a frequency based output provided by a Fourier transformer coupled to a sensing device to allow the spectral plotter to determine the power frequency spectrum of either the pulse-Doppler radar output or sensing device output. The HREE filter preferably comprises a bank of first order filters tuned to a pre-selected frequency, a covariance estimator coupled to the filter bank for estimating filter covariances, and a decoder coupled to the covariance estimator for producing a plurality of filter parameters. Further, it is preferable that the filters comprising the filter bank be adjustable to permit their being tuned to a desired frequency based on a priori information.
