| 摘 要： | 应用声压迭加原理，得到了参差调谐超声宽带基阵换能器的声压响应函数及声压指向特性，并应用波束等价的方法对波束分布的指向特性进行了优化模拟研究．通过对较优波束指向特性进行模拟，可以得到一个具有较优指向特性、布阵合理、阵元频率可参差调谐的宽带阵列换能器的布阵方案，为超声基阵换能器的设计提供了一个新途径．

| Abstract: | The acoustic pressure response function and directivity of the ultrasonic wideband stagger tuned array (UWSA) was obtained by means of acoustic iterated principle. The optimizing beam simulation of UWSA is made by equivalence. As a result,the designed scheme of UWSA was obtained and the directivity is better than that of even space linear array. |
