| 摘 要： | 将Rudin提出的红外成像捷联稳定模型用于天线平台的稳定,并应用不变性原理,采取匹配滤波方法,提高了稳定平台的解耦精度.具体仿真结果表明:在0.5?Hz~1.0?Hz频段解耦精度提高了35?dB.同时,在考虑传感器测量噪声的情况下,对天线平台的稳定误差进行了仿真分析,结果显示,传感器测量噪声对稳定误差有较大的影响,但通过滤波稳定误差可减小50%左右. |

| Abstract: | The strapdown stabilization model for imaging presented by Rudin was applied to antenna stabilized platform. Based on invariance principle, matching filter was used to stabilize antenna platform. The results show that decoupling precision is increased 35?dB at frequency 0.5?Hz~1.0?Hz. The impact of sensor noise on stabilization error also was simulated. Simulating results show that filter is practical in eliminating noise, and stabilization error can be reduced almost 50%. The technique used and results obtained are instructive for engineering problems. |
| Keywords: | stabilized platform strapdown gyroscope matching filter decoupling |
