The study on the targetradiation characteristic is base on the study on background radiation characteristic.
背景辐射特性研究是目标辐射特性研究的基础。

Through processing sound pressure combine with particle velocity, the information of underwater targetradiation noise field is entirely used.
通过声压与振速的联合信号处理,充分利用水下目标辐射噪声场的信息。

When the detection range of the IR thermal imager is calculated by using NETD, the targetradiation brightness difference must be calculated in the operating wave band.
