Firstly, the paper models the multivariable discrete state-space model of the air transmission unit by the lab method, using multi-dimensional inverse m series as input stimulus signal.
首先利用多维逆m序列作为激励输入信号，用实验法建立出空气传送部分的多变量离散状态空间模型。

Usually an inverse filter is designed and convolved with the signal, the objective being to nullify an objectionable effect of an earlier filter action.
通常是设计一个逆滤波器，然后与信号进行褶积，目的是使以前的滤波器对信号的影响变为零。

The inverse synthetic aperture radar (ISAR) echo signal model of fast-moving target and the effect of target fast-moving on ISAR signal processing were analyzed.
