全数字雷达仿真系统中恒虚警率模型的参数分析及设计

在实际的工程实践中,全数字雷达仿真系统建模中通常存在着设计参数输入不充分和客观环境模型建立的复杂度高两个问题,而这两个问题严重增加雷达系统仿真建模的难度。在此,以雷达仿真系统中的恒虚警率模型设计为例,提出对雷达模型中未知参数的推演及估算和复杂模型的替代模型结合,进行参数分析及设计思路。通过模型的边设计边验证的过程,分析并确认设计模型是否能够达到已知的关键性能指标要求,进而反向调整并确定设计的合理性。这种将模型建立和模型验证同步进行的设计方法,指导了某型号反潜直升机飞行模拟器的全数字多普勒搜索雷达的仿真实现。通过该实例应用,证明该仿真方法具备严谨性及实用性。

Parameter Analysis and Design of CFAR Model in DigitalRadar Simulation System

Abstract: In the actual engineering practice, We always have to face such problems just like insufficient design parameters input or established objective environment model that these two main problems seriously increased difficulty of the radar system simulation in practical engineering practice. In order to solve these problems, we take CFAR model design in radar simulation system for example. Here, the deduction and analysis of the unknown parameters in radar model is proposed so as to do parameter analysis and method design. Through the process of designing radar simulation model and do proving at the same time, we analysis and confirm the designed model which is able to achieve good compatibility or not, then we can confirm the rationality of design via feedback adjusting. This synchronous method of model establishing and proving has directed the digital Doppler search radar simulation realization in an anti-submarine helicopter flight simulator.Through the application of the anti-submarine helicopter flight simulator. It is proved that the design of radar simulation method with rigorous and practical.
