绕射传播 meaning in English

diffraction propagation
propagation by diffraction

High frequency surface - wave radar ( hfswr ) utilizes the surface - wave mode of vertical polarization electromagnetic wave propagation over sea water to detect targets of ships and aircrafts at distance beyond the line of sight
高频地波雷达( hfswr )依靠高频垂直极化电磁波沿海洋表面绕射传播的机理,实现对海面舰船目标和低空飞行目标的超视距探测。
The land clutter is useless signals for target detection caused by land terrain . the multipath effect is some kind of interference which is caused by wave reflection on terrain . the diffraction effect is the phenomenon of wave propagation into shadow region
地杂波是由地面散射引起的对目标探测无用的信号;多路径是由电磁波在地面反射所引起的干涉;衍射则是电波绕射传播到遮蔽区的现象。
In this paper , a quasi - 3d model of nearshore wave - induced currents and long waves is established based on the combination of an averaged integration of surface wave - induced currents equation along water depth , a 2d equation for the solution of vertical structures of the currents and a nonlinear parabolic approximate wave reflection - diffraction equation of mild slope
