| 摘 要： | 低能见度条件下的电力线探测对直升机低空飞行安全起着至关重要的作用。针对毫米波段电力线后向散射回波特征进行了理论分析,研究了天线极化对电力线回波的影响。在充分的理论分析基础上,确定了采用毫米波收发系统进行电力线探测的试验方法,得到了电力线回波数据。通过对回波数据分析,提出了一种电力线检测模型,通过仿真试验可清晰地检测到电力线,证明了毫米波收发电力线检测模型的正确性。

| Abstract: | It is important to detect power lines in low visibility environments for the safety of low-flying helicopters.In this paper,the electromagnetic scattering character of power lines at millimeter-waves is analyzed in theory,and the effect on scattering character of power lines from antenna polarization is researched.Based on the theory and analysis,an experiment at millimeter-wave is put forward to get the actual data of power lines,and the test scattering data of power lines are obtained.By the analysis of test,a power line detection model is presented based on the experiment,and the correctness of the model is proved by the detection result of the experiment. |
