摘要
在进行雷达目标仿真时要求运动目标既符合基本的运动定律又具有连续的加速度,传统雷达目标仿真方法无法同时满足这两个条件。针对此问题,提出一种基于目标运动定律的连续加速度雷达目标仿真方法。通过统计飞行器的性能参数,分析飞行器的运动定律,建立基本的运动模型;对基本运动模型进行随机组合生成目标运动轨迹;构建三次B样条曲线对目标运动轨迹进行平滑处理,计算目标运动参数。仿真结果表明,该方法能够生成既符合运动定律又具有连续加速度的仿真雷达目标。
Continuous acceleration and conformance to aircraft’s basic motion laws are required in radar target simulation.Tradi-tional radar target simulation method cannot meet these two conditions at the same time.To solve this problem,a radar target simulation method with continuous acceleration was proposed based on aircraft’s motion laws.By studying the motion characte-ristics of aircraft,the basic mathematics motion was established,and the simulate trajectory was generated by combining these basic motion models.B-splines were built to optimize the simulated trajectory and target motion parameter was calculated.Re-sults show the algorithm can generate radar target with continuous acceleration and conform to aircraft’s basic motion laws.
