Abstract： Using experimental data reflected by the sea on specific radar cross-section (SRCS) at millimeter and centimeter waves, the approximations of the wind speed, angle of the sea surface radiation and polarization of the incident field can be calculated. The simulation model of the scattered signal has been proposed on the basis of the semi-Markov nested processes. For the first time it has been proved that for the description of reflections at spikes and pauses, it is possible to use finite atomic functions. The proposed model allows us to estimate the backscatter intensity of millimeter and centimeter radio waves by the sea at grazing angle of surface radiation, as well as to simulate scattered signal.

摘要:本文利用海边反射在雷达横截面（RCS）上某些毫米波段和厘米波段的实验数据， 来计算风速、 海面辐射夹角和入射场极化的近似值， 并在马尔可夫半嵌套过程的基础上提出了散射信号的仿真模型。 本文证明了在反射尖峰和停顿状态的描述中可以使用有限原子式指令。 该模型可以估计海边毫米波段和厘米波段的无线电波以一定海面辐射掠射角的后向散射强度， 并且发出模拟散射信号。
