基于DSP的数字航姿模拟器设计

航姿模拟器是在对机栽设备进行地面测试时用来仿真飞机航姿信号的专门设备。传统航姿模拟器通用性差、控制精度低且不易与自动测试系统（ATE）接口。为此设计了基于DSP的数字航姿模拟器。该模拟器能同时输出航向、横滚及俯仰信号，可与计算机接口或直接嵌入自动测试系统，具有跟踪速度快、精度高、控制简单等特点。该模拟器在某型机载雷达ATE中获得应用。

A DSP based digital flight attitude simulator design

Flight attitude simulators are special devices to generate flight attitude signals for aircraft carried equipments ground testing. The traditional analog simulators are low precision, not generally applicable for different type of equipment and difficulty to interface to ATE, Thus a DSP based digital flight attitude simulator was designed. The simulator can generate high precision flight heading, rolling and pitch signals simultaneously with fast tracking speed. And it also can be connected to computer or embedded into an ATE system for easy control. The simulator has been successfully used in a radar ATE.
