动态雷达目标仿真中目标姿态角的计算

为了对动态雷达目标建立合适的数学模型,逼真地复现目标的运动特性和回波特性,从而实现动目标仿真,提出了利用野外真实试验中实际测得的目标RCS数据建立动目标仿真模型,实现动态雷达目标仿真的一种新方法.文章首先探讨了采用该方法对动态雷达目标RCS仿真的具体步骤,然后对实现仿真的一项关键技术--运动目标姿态角的求解进行了公式推导,并列举了应用实例,为进行良好的动态雷达目标仿真提出了一个新思路.要实现仿真还需要做许多工作,如对动态目标RCS起伏规律进行分析,计算统计参数,应用常见RCS起伏模型对目标动态RCS统计分布进行拟合等.

Calculation of attitude angle in dynamic radar target simulation

To build an appropriate mathematic model of dynamic targets tracked by radars and thus to reproduce the movement and echo characteristics of the target for realizing dynamic target simulation,a new method is put forward using radar data measured in real world environment.The simulation process of the radar cross section of dynamic targets is discussed.Then one of the critical technologies for simulation,the solution of the attitude angle of the moving target is studied.The attitude(heading,roll,yaw & pitch) of target can be derived from data in field tests and calculated with formulate.An example is used to demonstrate this method.Of course,many other jobs are necessary for realizing dynamic target simulation,such as undulation rule analysis, statistic parameter calculation etc.
