AN ACOUSTIC SIMULATOR FOR MODELING BACKSCATTER OF ELECTROMAGNETIC WAVES
Abstract
Model experiments are commonly employed in situations where full scale experiments are uneconomical and where exact theoretical analysis is very difficult. A study was made to develop techniques of using high frequency acoustic waves in water to simulate electromagnetic waves in air. The simulation technique is applied to radar and altimeter design problems as an aid in determining system parameters and to evaluate the performance of signal processing circuitry. It was determined that many of the statistical characteristics of electromagnetic waves scattered from terrain, such as: (1) the angular dependence of the mean backscattered power, (2) the range of fading, and (3) the rate of fading, can be duplicated using appropriate targets and acoustic waves in water.
