Radar signal digital pulse compression processing can be realized mostly by time-domainandfrequency-domain methods.
雷达信号数字脉冲压缩处理主要采用时域和频域两种方法来实现。

On time-domainandfrequency-domain aspects, steady and transient performances of the control system were considered to designing the LQG controller.
通过从时域和频域的角度分析，考察控制系统的稳定性、过渡响应特性，从而设计出了LQG控制器。
