摘要
海杂波是影响对海雷达目标探测性能的主要制约因素之一。从目标探测的需求出发,以削弱海杂波不利影响、实现精确制导为目的,建立海杂波模型并开展海杂波对雷达导引头的影响研究。通过仿真计算,分析了在海杂波的影响下,雷达设计参数及目标参数对飞行器俯冲角的影响,结果表明最大俯冲角度随着目标RCS、雷达口径、雷达频率的增大而增大,随着距离分辨率的增大而减小。结合飞行器与雷达工程设计方案,进一步给出了打击不同目标时的入射余角。
Sea clutter is one of the main limiting factors influencing the target detection performance of nautical radars.Based on the target detection requirements,the sea clutter model was established and the influence of sea clutter on radar seeker was studied for the purpose of reducing the adverse influence of sea clutter and achieving accurate guidance.By numerical simulation,the influence of the radar design parameters and target parameters on the maximum dive angle of the aircraft was studied.The results show that the maximum dive angle increases with target RCS,radar caliber,radar frequency,but decreases as radar range resolution increases.Combining aircraft and radar engineering design schemes,the principle of the grazing angle of attacking different targets is further presented.
