摘要
雷达成像制导是空空导弹雷达制导的重要发展方向,根据空空导弹末制导中导弹与目标的特点和机理,讨论了空空导弹弹载SAR的回波信号数学模型,建立了空空导弹弹载SAR仿真系统的回波信号构成原理和仿真系统,为空空导弹弹载SAR工程化研究提供了理想的原始回波信号数据.
The imaging pattern and algorithm for radar imaging seeker in airborne missile were proposed. Compared with the ground object imagery of tradition synthesis aperture radar, the air-to-air missile borne SAR has important characteristics including high flight speed, non-straight movement with non-constant velocity and big squint angle, which forward crucial requirements for the real-time performance, precision of the motion compensation. According to the motion of air-to-air missile and the target, the imaging pattern , algorithm and the digital real-time signal processing platform were designed.
