雷达信号级仿真中的模型耦合问题研究

摘要

针对目标回波小尺度幅度起伏特性模型进行了介绍.对雷达线性接收机和对数接收机的特性和模型进行了对比.对雷达信号级仿真中,由于雷达采用非线性对数接收机造成的目标回波小尺度幅度起伏特性模型与接收机模型相互耦合的原因和所产生的影响进行了分析.提出对这样的模型耦合问题必须解决,以保证仿真研究结果的有效性.%In this paper, the target echo ripple model is explained. The features and models of radar linear receivers and log receivers are compared. The cause of target echo ripple model coupling with receiver model and the effect in radar simulating on signals are analysed. In the end, point out, in order to ensure the validity of simulation research, the model coupling problem must be resolved.
