本文根据经典控制理论,论述了激光导引头的分析和综合方法。文中说明了激光导引头的数学模型应该是离散型的。文中建议将激光指示误差当作导引头的主要输入噪声,据此进行回路的最佳综合,导引头将具有某种抑制激光指示误差的能力。还建议以跟踪回路的质量要求作为回路综合的依据。计算结果表明,导引头回路的增益和激光重复频率对导引头的性能影响很大。
Based on classical control theory, this paper discusses the analysis and synthesis of laser seeker. The paper shows that the mathematical model of laser seeker should be discrete. In this paper, the laser pointing error is suggested as the main input noise of the seeker, and the best synthesis of the loop is made accordingly. The seeker will have some ability to suppress the laser pointing error. It is also recommended to follow the loop quality requirements as a comprehensive basis for the loop. The calculation results show that the gain and laser repetition frequency of the seeker loop have a great influence on the performance of seeker.
