Ku波段海表波高／潮位探测系统的研究 |

| [摘要] |
| 本文提出的Ku波段海表波高／潮位探测系统在测量精度和使用方便上优于沿用至今的波高计和浪潮仪。该探测系统为－机两用，使14．5GHz微波信号通过两只检相管比较Doppler回波相位，而精确测得波高，使11GHz微波信号通过三角波调频的相干差频可精确测得海表潮位。基于两路信号共用一部天线，采用正交极化工作且各插入带通滤波器，使隔离度在80dB以上，相互串扰抑制到很微弱，确保了测量精度在cm级，使实测值与定标值良好一致。 |

| A new Ku-band souding system for measuring wave-height and tide-level is proposed in this paper. It is better than the wave-height meter or wave-tide meter in precision,and is easy to operate. Two functions of the sounding system are:It can accurately measure the waveheight through comparing the phase of the 14GHz Doppler echoes passing through the two phasedetector diodes. The tide-level can also be measured accurately through coherent differential frequency of triangular wave modulated llGHz FM signals . Since the signals of the two channels are cross polarized and each channel is inserted with BPF respectively,the isolation between two channels is over 80dB, and the cross talk is very weak. The measurement precision lies in cm order,and the measured value is consistent with the standard one. |
