The sample can be introduced into the SVA through the top-lid e. g. with the help of a spatula, using the front part of the opening .

样品可以通过顶部的小开口进行添加。例如用一个小抹刀把样品填入前部的小孔。

Combination of the SVA and time-frequency analysis in ISAR imaging of the maneuvering target is proposed to improve imaging quality of the traditional RD algorithm.

在此基础上，提出将两者联合运用到机动目标的逆合成孔径雷达成像中，改善了传统的距离-多普勒算法对机动目标成像的模糊现象。
