Spatial&Temporal Correlation Analysis of Sea Clutter Based on Real Radar Data
摘要
Abstract
The correlation characteristics of sea clutter are time-dependent and spatial-dependent, which both are related to radar system parameters, environmental conditions and other factors. In this paper, the X-band real sea clutter data were used to study the temporal correlation of sea clutter under different polarizations, as well as the distance-spatial corre?lation and azimuth-spatial correlation respectively on the typical high and low sea conditions and at different grazing an?gles. The experimental results showed that the polarization had little effect on the time correlation of the sea clutter, the dis?tance-spatial correlation of the sea clutter was greatly influenced by the sea condition, and the azimuth-spatial correlation of the azimuthal adjacent resolution unit was weak. These conclusions are of great significance to the optimization of target detection method in sea clutter.关键词
