Available in PDF, EPUB and Kindle. Book excerpt: The performance of ground-based radars is affected by the spectral characteristics of ground clutter. Most signal processing algorithms designed to enhance detection performance are Doppler-frequency-sensitive, such as the moving target indicator filter, Doppler processor and coherent clutter map. This report gives the results of a comprehensive spectral analysis of low-angle ground clutter, using the MIT Lincoln Laboratory Phase I data and the DREO S-band clutter data. The report presents the spectral analysis of ground clutter for different bands of radar frequency; describes the data used in the spectral analysis, including both the conventional Fourier analysis and a super-resolution spectral analysis technique; gives a brief background on the maximum entropy spectral estimate; and describes the particular procedure designed to bring out the spectral characteristics of ground clutter from short time series.
