摘要: 为了解决半捷联成像导引头视线角速率直接提取噪声大的问题，首先分析了半捷联导引头视线角速率随机噪声的来源，建立半捷联稳定跟踪控制回路的模型，推导出各种误差与输出之间的传递特性。在主要的随机误差源统计分析的基础上，得出主要噪声的功率谱响应，依据功率谱响应对半捷联视线角速率各构成部分进行加权得出加权视线角速率。为了验证加权视线角速率的有效性，在制导回路中进行分析仿真，结果表明：加权方法能够有效抑制导引头测量信息的噪声。以半实物的方式实现半捷联电视导引头，在电视导引头完成双闭环后进行扰动隔离及跟踪靶标，将加权视线角速率提取方法提取制导信息与直接提取方法进行比较，实验结果表明，加权提取方法的视线角速率噪声均方差为0.098 ()/s，比直接合成噪声降低了46%。综上所述，加权方法可以很好地改善半捷联视线角速率噪声大的问题。

Abstract: To depress the guidance message noise of air-to-surface semi-strapdown imaging seeker, the control loop model of stability tracking was established, the transform characteristic of various error and output was derived. The power spectrum response of main noise was obtained. Then, the weighted angular rate of line of sight was gained. In order to verify the validity of the weighted angular rate of line of sight, the simulation were completed in the guidance loop. The results show that the weighted method can effectively compressed the noise measurement information of seeker. The semi-strapdown TV seeker was achieved with semi-physical way, the double closed-loop was completed in TV seeker to make disturbance isolation and track the target. The methods for extracting guided information through weighted angular rate of line of sight and direct extraction methods were compared. The experimental results show that the weighted extraction method of line of sight angular rate noise variance is 0.098 ()/s, which is lower than the direct synthesis of noise of 46%. The weighted method can improve the problem of large semi-strapdown sight angular rate noise.
