根据单兵武器捷联导引头的特点，提出一种弹体追踪和比例导引相结合的制导律。利用导引头的误差角信号和姿态陀螺的姿态信号，通过微分网络提取弹目视线角速率，实现比例导引部分，误差角信号作为姿态驾驶仪的输入完成弹体追踪部分。其次，利用根轨迹方法给出一种姿态驾驶仪设计方法。通过数学仿真可以证明，该制导律和姿态驾驶仪相结合，可实现精确命中目标，并具有良好的动态特性。最后，为论证MEMS陀螺和惯性陀螺等实现姿态驾驶仪的可行性，提出半实物仿真试验方案，作为理论设计进一步的验证手段。

According to characteristic of strap-down seeker for individual weapon, a guidance law combing proportional guidance with body-tracking guidance was proposed. By using the error angle signal output of the seeker and the attitude signal from the posture gyro, the angu-lar rate of the line of sight was obtained through differential network. The proportional guidance and the projectile tracking guidance were completed with input of the angular rate and the error angle signal for the autopilot. Besides, an elucidated design method for the autopilot of root locus method was given and general feature of the autopilot were also analyzed. The rationality of the new guidance law and the de-sign method of the autopilot was verified through mathematical simulation. High hitting accuracy can be realized and good dynamic charac-teristic was gained. Finally, in order to demonstrate the feasibility of MEMS gyro and inertial gyro, a hardware-in-the-loop experimental scheme was presented for further demonstration of the design.
