这种关系表明雷达可用的信号带宽是有一定限制的，随着工作频率的下降和成像斜角的增大，可用的信号带宽会变得越来越小。
The relationship shows that the maximum bandwidth is limited for these algorithms and becomes narrow when the center frequency is lower and the imaging squint angle is larger.
结果发现，质量、红移及旋转频率对相应状态方程质量-半径关系的简单限制很难区分不同的中子星模型。
We discover that it is hard for us to distinguish different neutron star models by the simple constraints of masses, redshifts and rotations on mass-radius relations.
