A NEW ACOUSTIC RADAR EQUATION Ravi M. Khanna In acoustic radar systems ; in order to estimate the received signal strength, it is a common practice to apply an electromagnetic wind profiler ( emwp ) equation , after modifying it to include the acoustic sounding parameters. The use of this modified equation , however, involves caution ; as the antenna concepts and the radiated signals , in the two cases, are not quite identical. In the new equation, an attempt has been made to combine the concepts of acoustics and those of electromagnetic radar , and use specifically measured antenna characteristics, to directly arrive at an expression which would enable us to estimate the received signals with better accuracy.
