1) split beam
分瓣波束
3) beam split
波瓣分裂
1.
The beam of VHF radar is rather wide,and the reflection from ground results in beam split,thus the radar can only be used to estimate its height while it cannot be used to measure the height accurately.
米波雷达的波束较宽、由于地面反射引起波瓣分裂,通常只能估高而不能用来测高。
2.
In this paper,the effect of landform on the heightfinding method based on beam split in VHF Radar,namely,phase comparison and amplitude comparison,is studied.
针对基于波瓣分裂的米波雷达"比相-比幅"测高方法,研究地形对米波雷达测高的影响。
3.
To resolve this problem,the paper proposes an accurate and effective method for measuring the altitude based on beam split,namely,Phase-comparison and Amplitude-comparison.
针对米波雷达的波束较宽、由于地面反射引起波瓣分裂,通常只能估高而不能测高这一难题,提出一种基于分裂波瓣的米波雷达低仰角测高方法——比相比幅法。
4) sidelobe level beamwidth
旁瓣级波束宽度
5) beam lobe switching
波束瓣转换法
6) Split beam
分裂波束
1.
The deepwater net-cage acoustic monitoring scheme described in this paper can monitor the feeding and growing of the reared fish in real time and can evaluate the total biomass increasing in the cage at all times,by using high frequency,narrow impluse,split beam and computer technology.
