由于超增益阵具有尺度小、空间增益高的特点，对于改进低频被动声纳的检测性能具有重要的意义。
Therefore, supergain hydrophone array, particularly the small-sized circular array, is very good for improving the detection performance of low frequency passive sonar.
螺旋天线不仅在宽频带上具有近乎一致的电阻性输入阻抗，而且在同样的频带上按超增益端射阵的波瓣图工作。
Helical antenna has not only almost identical to the resistive input impedance in broad bandwidth, but also works by the end of super-gain front lobed map in the same frequency band.
