【 摘 要 】

References(13)A multi-beam forming method was proposed for parametric array research. It was supposed that by this method, parametric array could generate a difference frequency wave containing multiple sub-beams. In order to verify the feasibility of the method, simulation and experiments were conducted to generate a difference frequency wave containing double sub-beams. As seen from the test result, the generated difference frequency waves present a double sub-beams shape. In addition to the partial overlap that exists between the sub-beams, the experimental data matched the anticipated results well. Therefore, the proposed multi-beam forming method was proved to be effective and feasible.
