grazing approach angle切线进入角
grazing incidence angle掠入射角
grazing g angle入射余角
beam grazing angle波束掠射角
high grazing angle大入射余角
high-grazing angle高入射余角
critical grazing angle临界掠射角
low grazing angle低入射余角下
The monostaic passive location systems are actually bistatic radar systems. The direct wave and the ground clutters propagate at low altitudes with small grazing angle, and affects the coverage varies with the length of base line.
基于调频广播的单站无源定位系统实际相当于收发分置的双基雷达,其直达波和地杂波的传播为小擦地角的低空传播,且影响威力范围的因素随基线长度的变化而有所不同。
