位标器的跟踪性能由跟踪信号驱动形成的周期平均力决定,跟踪收敛性是位标器跟踪性能的重要体现。应用级数理论分析了位标器的跟踪收敛特性,得出了位标器的跟踪收敛性受到位标器跟踪系数k和跟踪相位误差△影响的结论。并通过计算给出了位标器跟踪的收敛条件和收敛步长,即随着跟踪系数k与1的偏差△k及跟踪相位误差△增大,跟踪收敛步长也会相应增大。这些结论会给位标器跟踪算法的设计提供重要的理论支撑。
位標器的跟蹤性能由跟蹤信號驅動形成的週期平均力決定,跟蹤收斂性是位標器跟蹤性能的重要體現。應用級數理論分析瞭位標器的跟蹤收斂特性,得齣瞭位標器的跟蹤收斂性受到位標器跟蹤繫數k和跟蹤相位誤差△影響的結論。併通過計算給齣瞭位標器跟蹤的收斂條件和收斂步長,即隨著跟蹤繫數k與1的偏差△k及跟蹤相位誤差△增大,跟蹤收斂步長也會相應增大。這些結論會給位標器跟蹤算法的設計提供重要的理論支撐。

The tracking convergent property is an important guideline for a reticle seeker. The tracking of the reticle seeker is driven by the period mean torque which is generated by the tracking signal. In this paper, the convergent property of the reticle seeker was analyzed and some significant conclusions were attained using series theory. The convergence of the tracking procession was affected by both the tracking coefficient and the phase bias △ between the target location and the tracking signal. The convergent conditions and the convergent step function were also obtained. These conclusions are important for the design of the convergent tracking algorithm of the reticle seeker.
