采用“面向控制”模型的建模新方法——频域线性算法,对采用比例导引的主动式雷达导引头进行建模。此算法可辨识出对象模型和模型偏差的硬边界。针对主动式雷达导引头使用环境恶劣,以及导引头与目标、环境相互作用关系复杂,使用了调整的频域线性辨识算法(即需要先验知识)。仿真计算表明,此辨识算法鲁棒性好,辨识可信度高 An active radar seeker with proportional guidance is modeled by the frequency-domain linear algorithm, a new modeling method of “control-oriented” model. This algorithm identifies the hard boundaries of the object model and model deviations. In view of the harsh environment of active radar seeker and the complicated interaction between seeker and target and environment, a modified frequency domain linear identification algorithm (ie prior knowledge required) is used. Simulation shows that this algorithm has good robustness and high credibility
