带落角约束的圆弧比例导引律和偏置比例导引律的研究

为了实现导弹以一定落角命中目标，研究了两种带有落角约束的圆弧比例导引律和偏置比例导引律。首先建立弹目相对运动数学模型和框架动力学数学模型，然后阐述了两种导引律的基本原理，接着对导弹在三维空间内攻击静止与运动目标进行数学仿真试验，仿真实验证明两种导引律都能以较小的脱靶量和期望落角命中目标，最后从原理上和仿真实验上对两种导引律进行了对比研究。

Research on Circular Navigation Guidance Law and Biased Proportional Navigation Guidance Law with Impact Angle Constraint

In order to intercept against a target with a certain impact angle, we study two angle constraint guidance laws called circular navigation guidance (CNG) and biased proportional navigation guidance (BPNG). Firstly we establish the relative motion dynamic model and the gimbaled dynamic model. Then we explain the basic principles of the two guidance laws and use computer simulations to test three-dimensional intercepts against a moving or stationary target. We prove that the two guidance laws have been shown to give perfect results in miss distance and desired impact angle. Finally we present a comparative research of the two guidance laws on principle and simulation experiment.
