振动对弹载SAR中心运动参数影响研究

Influence of vibration on missile-borne SAR motion parameters

为了对导弹的杆臂效应进行分析,在考虑弹载SAR导弹费效比的前提下,设计SAR平台不带有惯导设备,考虑直接利用弹上惯组输出的运动参数信息,通过计算分析得到SAR天线中心实际的运动信息,用于SAR天线中心的运动补偿.建立了考虑振动和杆臂效应影响的惯导到天线中心的运动传递关系,并根据给出的典型弹道和振动情况进行仿真验证分析.

To study the lever-arm effects of missile, considering the missile missile-borne SAR under the premise of cost-effective, and the direct use of the motion parameters output from missile＇ s IMU, this paper designed SAR platforms without INS equipment, and got the actual SAR antenna center movement informa- tion, which was used to the SAR antenna center movement compensation. The motion transfer relationship of initial navigation to the antennary center was built up by considering of the vibration and lever-arm effects, and simulation analysis of validation was made.
