A capture region of the composite guidance law is analyzed for a missile equipped with a strapdown seeker. The composite guidance law consists of a deviated pure pursuit guidance law and a pure proportional navigation guidance law to perform impact-angle control. The range of the field-of-view limit restricts the performance of the guidance law, which reduces the capture region. Based on the characteristics of the guidance law, the range of the achievable impact angle is investigated by considering the collision condition and the field-of-view limit. It is shown that the capture region is represented in terms of the relative initial position and terminal flight-path angle. Numerical simulations are performed to investigate the properties of the proposed capture region of the composite guidance law.

考虑视场限制的冲击角控制复合制导律的可捕获性

针对装有捷联导引头的导弹，分析了复合制导律的俘获区域。复合制导律由偏航纯跟踪制导律和纯比例导航制导律组成，进行撞击角控制。视场限制的范围限制了制导律的性能，从而减少了捕获区域。基于制导律的特点，考虑碰撞条件和视场限制，研究了可达到的碰撞角度范围。结果表明，捕获区域用相对初始位置和终端飞行路径角表示。进行数值模拟以研究所提出的复合制导律捕获区域的特性。
