| 摘 要： | 针对现阶段困扰低纬度地区高频地波雷达发展的电离层干扰问题,分析了电离层的干扰特性,提出双基地体制下利用收发之间的位置相互关系减小高仰角区的电离层干扰的方案;通过对发射天线进行优化设计,增加天线在俯仰维的孔径,减小向上的能量辐射,达到降低电离层干扰的目的.仿真验证了该方法的有效性.

| Abstract: | The anti-ionospheric interference technique was studied which is used for coast/ship bistatic high frequency surface wave radar(HFSWR).At present,the ionospheric interference prevents the development of HF OTH(over the horizon) radar.The characteristics of ionospheric interference were analyzed,and the method was presented for reducing ionospheric interference received from high elevation angles by using the relationship in position between transmitter and receiver.Furthermore,the optimized design of transm... |
