| 摘 要： | 蒸发波导是海洋大气环境中出现频率最高的波导,利用蒸发波导实现超视距探测是扩大雷达测量范围的一种特殊方法.其中,雷达实现超视距探测的条件是关键问题之一.根据电波传播理论和蒸发波导特征,从蒸发波导的判别、雷达工作波长和频率、电波射线的初始发射角,以及雷达天线所处的位置等方面分析了雷达实现超视距探测的必要条件.结果表明,要实...

| Abstract: | The highest frequency duct is evaporation duct under marine atmospheric environment,and it is a special method of expanding the radar measuring range by using the evaporation duct to achieve the over-the-horizon detection.On what conditions to ensure the realization of the over-the-horizon radar detection is one of the key problems.Many aspects,such as evaporation duct discrimination,radar operating wavelength and frequency,initial launching angle and the location of radar are studied to get the necessary c... |
