联合直接攻击弹药精确制导技术分析

Analysis on Guidance Technique of Joint Direct Attack Munitions

从技术分析的角度对联合直接攻击弹药(JDAM)的武器制导系统进行了研究。安装JDAM制导控制装置的弹药武器,通过GPS/INS组合制导和尾翼调节,控制武器精确命中目标。在对JDAM系统组成和精度分析的基础上,详细讨论了JDAM系统的卡尔曼滤波器、捷联惯性导航技术、传递对准和GPS辅助惯性制导等技术。对设计中遇到主要的技术难点和相应的解决途径也进行了分析。

This paper focuses on the design of munitions guidance system of joint direct attack munitions(JDAM). The guidance unit is attached to the bomb, and through controlled tail fin movements, directs the bomb to the target. The Kalman filter, SINS technique, transfer alignment and GPS-aided navigation in JDAM system are analyzed based on the system composition and accuracy analysis. The design of the INS, the configuration and operation of the Kalman integration filter are also presented carefully.
