摘要
由于与系统配置的密切关系,双基地雷达系统在建模时具有较大的不确定性。从传统单基地雷达的建模方法入手,利用几何分析的方法,建立了目标向双基地雷达发射站直行临近的低空目标回波模型,并对其进行了精度分析;在此基础上,进一步得到了矩形脉冲信号模糊函数的数学表达式及模糊图,从而为双基地雷达的低空目标建模和性能分析提供了一条新思路。
The model of bistatic radar system is of great uncertainty as a result of close relation to system configuration.Starting from the modeling of conventional monostatic radar and using the given configuration as constraint condition,the paper made an echo model of bistatic radar with a target straightly approaching the transmitter at low altitude and its precision analysis.On the basis,the mathematical expression and ambiguity picture of ambiguity function of a rectangular pulse signal were obtained and thereby,providing a new method for setup of a target model at low altitude of bistatic radar and the system performance analysis.
