摘要:
机载SAR中,天线稳定平台是为了消除载机飞行姿态变化对成像影响的关键设备。目前的天线稳定平台一般将陀螺仪安装在稳定平台上,由于受到高空低温、高湿和电机磁场等的干扰,稳定平台对其陀螺仪的工作精度和可靠性要求很高,对其防护要求也很高,增加了平台制造的难度和成本。本文提出将陀螺仪安装在载机内部,通过建立和分析陀螺仪矢量变换数学模型,能够正确获得稳定平台三轴上对应的角速度信号,并得到实验数据的证实。
Abstract:
In the airborne synthetic aperture radar(SAR), the stable platform of antenna is key equipment to eliminate the influence of aircraft attitude variation on the imaging. At present, the gyroscope is commonly settled on the stable platform. Unfortunately, due to the disturbances of low temperature and high humidity at high altitude as well as the magnetic field of motors, the particularly high accuracy and reliability of the gyro are required by the platform, and the protection for the gyro is also very strict. These make it difficult and costly to manufacture the platform. A method is proposed in this paper to set the gyro into the aircraft interior, and the angular velocity signals of the three-axis stable platform are correctly acquired by establishing and analyzing the mathematics model of gyro vector transformation, and it is verified by the experimental data.
