摘要
在雷达装备的数字仿真建模领域,信号级模型和功能级模型在运行效率和细粒度仿真方面往往存在不可兼得的情况。本文基于信号和噪声的概率统计特性,以及信号处理的机理,以脉冲压缩雷达为例,构建了叠加噪声并经过信号处理后的检测包络模型,并给出了具体的实现方法。这种方法可以在进行雷达功能级建模时,替换原有的基于信噪比的目标检测方法,能够提升模型逼真度并支撑装备的细粒度仿真。
In the traditional area of digital modeling of radar equipment,signal-based model and function-based model cannot have both ability of high efficiency and deep simulation. This paper gives an new method of modeling of radar signal,which is calculate and compose the final envelope of pulse-compression radar signal processed by the core module. This method can replace the old method simply based on SNR,and can be used directly in the function-based radar model. The improved model will have high-fidelity and support deep simulation.
