摘　　要：基于MEMS加速度计,研究和设计了一种无人机弹射器参数测量系统。通过对传感器标定,校准了其零偏、灵敏度等参数,实际使用时对误差进行补偿,提高了测量精度。根据实际加速度信号特点,选择合适的带宽和采样频率,并设计了数字滤波器,在保证响应频率的同时,有效降低了噪声。实验证明:本系统不仅达到了技术要求,而且与其他测量方式相比,有效地降低了成本。Based on micro-electro-mechanical system（MEMS）accelerometer,a parameter measurement system for unmanned aerial vehicle（UAV）catapult is researched and designed.By calibrating the sensor,calibrates its zero-offset,sensitivity and other parameters,compensate error while utilizing,and improves its precision.According to characteristics of actual acceleration signal,select proper bandwidth and sampling frequency,designs digital filter,while assure response frequency,at the same time,effectively reduce noise.Experiment show that the system not only reach technical requirement,but also reduce cost effectively,compared with other measurement modes.
