| Abstract: | We examine a method for estimating the transient impedance of an emitter and a receiver in a free field based on sliding complex
averaging of the frequency dependence of the transient impedance of the emitter and the receiver obtained under continuous
emission in an undamped pool. The method makes it possible to weaken the influence of reflected signals and to obtain frequency
characteristics almost coinciding with measured ones in free-field conditions. We present results from experimental studies
of the method and its application for calibration of hydrophones by field with the reciprocity method in a reverberating field. |
