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.

- 聲表面波濾波器(SAWF)是一種性能優(yōu)良的新型電子器件,本文基于SAW濾波器的帶通濾波性質(zhì),設計了一種新的SAW加速度計系統,它不僅實(shí)現了判斷加速度方向的客觀(guān)需求,而且為加速度計基本量程的擴大創(chuàng )造了條件。
