A Design Proposal for an Inexpensive Parametric Array

Abstract

In this technical memorandum, the fundamentals of the physics that govern the operation of parametric arrays are discussed in a non-mathematical way. The governing relations for a piston source as derived using linear theory are also discussed. These relations are contrasted with those that govern the source level and beamwidth of the parametric array which is linear absorption limited in the collimated zone near the source. A simple design for a low cost parametric array is presented, and its advantages and disadvantages are discussed.
