The results showed that the radial frequency was greatly affected by the height of the cross-section, but the tangential frequency wasn't.

结果表明：截面高度对径向振动频率有显著影响，但是对切向振动频率影响很小；

In an array consists of 27 combination vibrators, a strong coupling mode of axial and radial vibrations presents in the intermediate frequency range.

在由27个组合振子构成的阵列中。居间频率范围内出现一个轴向和径向的强烈耦合模。

The purpose of autofocusing is to remove the radial motion effect of the target from radar echoes, and only reserve the stepped frequency effect which is the basis of synthetic HRR capability.

自聚焦的目的是从雷达回波中消除目标径向运动的影响，只保留步进频率的影响，而后者是合成hrr能力的基础。
