Abstract
Sea-clutter has been and continues to be a major source of performance limitations for maritime surveillance radar systems. An understanding of the detailed sea-clutter behaviour is important in devising signal processing algorithms aimed at optimizing radar detection performance under sea-clutter environments. A sea-clutter measurement experiment was conducted in July 1982 at North Truro (near Cape Cod), Massachusetts. The radar equipment employed was a multi-frequency, mobile coherent radar operated by Lincoln Laboratory of the Massachusetts Institute of Technology(MIT). Sea-clutter data were collected at X, S, L, UHF and VHF bands. Because of interferences on the UHF and VHF bands, only X-, S- and L-band data are analyzed. Analyses have been carried out examining the sea-clutter coefficient as a function of frequency, polarization and waveform resolution. Spectral characteristics of sea-clutter in up-wind, cross-wind and down-wind conditions are compared.
