为了提高远程反舰导弹的巡航制导能力,增大有效射程,在对未来海战场特点和相关技术背景进行客观分析的基础上,结合小视场天文导航技术的特点,提出了以天文测角导航技术作为中远程导弹巡航阶段主要制导手段的制导方法,提出了“制导角”的概念,给出了系统设计,列举了系统的技术优势。制导系统分为三个阶段,即初始参数装订与计算、制导角修正和末制导确认,分别给出了计算公式和相关推导,并用数学计算工具对一个想定情况进行了仿真计算。仿真结果表明,制导角连续可用,系统误差在可控范围之内,系统可以有效进行巡航制导。
In order to improve the cruise guidance capability of long-range anti-ship missiles and increase the effective range, based on the objective analysis of the characteristics of the future maritime battlefield and related technical background, combined with the characteristics of small-field astronomical navigation technology, As the guidance method of the main guidance means for the long-range missile cruise phase, the concept of “guidance angle” is put forward. The system design is given and the technical advantages of the system are listed. Guidance system is divided into three stages, namely, the initial parameters of binding and calculation, guidance angle correction and final guidance confirmation, respectively, given the calculation formula and derivation, and a mathematical calculation tool to simulate a situation. The simulation results show that the guidance angle is continuously available and the system error is within the controllable range, and the system can effectively perform cruise guidance.
