A novel method of simulating the sea surface was proposed in this paper, which employing the Bragg structures to control the mono-static reflectivity coefficient at certain angles, namely, the grazing angles is typically from 50° to 30°. The compared results between the simulated and measured data showed that the mean square error (MSE) is less than 3dB, which meant that the new method was very useful.
The model of GTI, TSC, NRL distribution the most fundament characteristic of sea clutter, as used in radar performance evaluation. The model of Rayleigh, LogNormal, Weibull and K distribution radar clutter are analyzed and modeled and some kinds of radar clutter, such as ground, weather, chaff and sea clutter are modeled and simulated. The analysis focuses on amplitude characteristic of sea clutter...
Based on the co-polarized ratio and the co-polarized discrimination ratio of the back scattering coefficient, the inversion of the dielectric constant is discussed in this paper. The value of the co-polarized ratio and the co-polarized discrimination ratio are calculated for minimum effect of surface roughness for the retrieval of the dielectric constant. The ratio of the co-polarized and co-polarized...
The characteristics of composite backscattering from a target above a one-dimensional and two-dimensional oceanic surface are investigated with the diffraction of the target fringe taken into account. The backscattering radar cross section (RCS) of the oceanic surface is calculated by the Small Slop Approximation (SSA). The backscattered field of a target is computed based on the equivalent edge currents...
