双基地雷达沿基线目标模型的建立及零多普勒区的划分

Establishing Model and Plotting Zero Doppler Regions for Moving Targets Along Bistatic Baseline

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 idea of establishing monostatic target model, the echo model for a moving target model along bistatic baseline was established by the theory of analytic geometry. The moving target model along bistatic baseline is a special situation of general bistatic target＇s echo model. The establishment of the model lays an analytical foundation for dividing zero Doppler areas on the bistatic baseline while a model established by Tsao T doesn＇t possess above-mentioned feature. Besides the feature, no complex reference system is required for the model in the paper. It provides a new idea for analysing ambiguity function.
