| 摘 要： | 针对短基线前向散射雷达系统特性,基于阴影逆合成孔径原理和模糊函数,分别推导了系统沿基线方向和垂直基线方向运动目标的分辨率,解析得到了系统分辨率计算公式;发现垂直基线方向分辨率正比于波长,并首次验证了前向散射雷达沿基线方向分辨目标的可能性;最后利用实测数据验证了沿基线方向和垂直基线方向分辨率分析的正确性.

| Abstract: | According to the system characteristic of short baseline forward scatter radar （FSR）, using the prin- ciple of shadow inverse synthetic aperture radar and ambiguity function, the resolution along baseline direction and crossing baseline direction are derived and analytically obtained. It is found that the resolution of crossing baseline direction is proportional to signal wavelength, furthermore, the resolution possibility along baseline di- rection is demonstrated at first time. Finally, the correctness of resolution analysis is verified via the experimental data. |
