The elementary principle is to make use of the band pass characteristic of surface acoustic wave filter (SAWF) choose SAW signal matched the direction of acceleration. This plan is also a base for enlarging measure range of SAW accelerometer.

• 声表面波滤波器(SAWF)是一种性能优良的新型电子器件,本文基于SAW滤波器的带通滤波性质,设计了一种新的SAW加速度计系统,它不仅实现了判断加速度方向的客观需求,而且为加速度计基本量程的扩大创造了条件。
