根据建立单基地雷达运动点目标回波模型的分析思路,运用解析几何的方法,建立了双基地沿基线运动目标的回波模型。沿基线运动目标模型是一般双基地雷达回波模型的一种特殊情况,该模型的建立为双基地基线零多普勒区的划分提供了分析基础,这是Tsao T所建一般模型所不具备的。模型的建立无需复杂的指北坐标系,为模糊函数的分析提供了一条新思路。 According to the analysis idea of ​​establishing target echo model of single-base radar point-of-motion, the echo model of bistatic movement along the baseline is established by using analytic geometry method. The moving target model along the baseline is a special case of the general bistatic radar echo model. The establishment of this model provides the basis for the division of the zero-Doppler region of the bistatic baseline, which is not available in the general model built by Tsao T of. The establishment of the model does not need a complicated north coordinate system, which provides a new idea for the analysis of fuzzy functions.
