1) cosecant
余割
2) cosecant kernel
余割核
1.
As the inversion problem for singular integrals with cosecant kernel usually has no solution in case of index k<0, we proposed and solved two different new forms of modified inversion problem in this paper.
针对含余割核奇异积分反演问题在指标k<0时一般无解的情况,本文提出并求解了两种修改的反演问题。
3) arc cosecant; inverse cosecant
反余割
4) cosecant antenna
余割天线
5) recurrent secant approach
循环余割法
6) csc2θ shaped beam
超余割赋形波束
1.
The csc2θ shaped beam for radar array antenna is synthesized using symmetrically and implicitly constrained method,which can obtain the optimal shaped beam by controlling the ripple amplitude in the shaped region.
提出了一种用于雷达阵列天线的超余割赋形波束综合方法——间接对称约束法。
