Research on Target Calibration Method of Photoelectric Missile

摘要:

针对光电制导导弹高精度指向需求，通过研究导弹校靶方法以修正系统误差，提升光电导引头指向精度。提出解析法和几何法两种校靶方法，解析法是从数学推导的角度出发，利用坐标等效变换列写方程组，通过求解多元方程组获得校靶修正角度；几何法是从距离逼近的角度出发，通过多点测量实际指向误差，利用最小二乘、几何旋转变换等方法得到校靶修正角度。最后利用数字仿真分别模拟了两种校靶算法，并进行了对比分析，验证了两种算法的有效性。

Abstract:

Aiming at the high-precision pointing demand of photoelectric guided missile, studies the method of missile target calibration to correct the system error and improve the pointing accuracy of photoelectric seeker. Two calibration methods, analytical method and geometric method, are proposed. Analytical method is based on mathematical derivation, using coordinate equivalent transformation to get equations, and solving multiple equations to obtain correction angle; geometric method is from the perspective of distance approximation, through multi-point measurement of actual pointing error, using least square, geometric rotation transformation and other methods to get the correction angle. In the end, two kinds of target calibration algorithms are simulated by numerical simulation, and the effectiveness of the two algorithms is verified by comparative analysis.
