| 摘 要： | 建立了双基地雷达的空间几何模型,基于双基地雷达LFM脉冲信号的模糊函数,导出了其距离分辨力和速度分辨力的关系表达式.理论分析和仿真结果表明双基地雷达LFM脉冲信号的距离分辨力和速度分辨力与目标双基地角有关,减小接收基地视角和短基线长度可以获得高的双基地雷达分辨力.

| Abstract: | Space geometry model of bistatic radar is presented first in this paper.Based on this the ambiguity function of LFM pulse signal for a bistatic radar is derived in detail and the range resolution and velocity resolution of LFM pulse signal for a bistatic radar are analyzed.Theory analyse and simulation results suggest that the range resolution and velocity resolution are the function with respect to the bistatic angle,and little look angle of the receiver and short baseline can obtain high resolution. |
