术语“冲激响应函数”的详细信息

英译术语:

impulse response function

汉语语境:

水声信道的冲激响应函数和频率响应函数只与收发位置及水文条件有关，与信号形式无关。超声图像分辨率低的主要原因是由于被测组织的反射分布函数与超声系统的冲激响应函数(或称“系统函数”或“点扩散函数”)卷积的结果。

英语语境:

The impulse response function and the frequency response function of the underwater acoustic channel are only in contact with the position of the sources and the receivers, velocity profile and depth of water, not with the form of the signals. The reason of the low resolution in ultrasound images is primely due to the convolution between the reflection of the detected tissue and the impulse response (called “System Function” or “Point Spread Function”) of the ultrasound system.
