| 摘 要： | 提出了一种可用于船(舰)载的Ku波段微波波高计,它是一种非接触式的波高测量设备,可架设于船头,动态测量海浪波高参数.为了修正船体颠簸对测量结果的影响,在微波探测单元上设置了加速度传感器,提出了两种不同的数学模型——加速度匀变模型和简谐振动模型,分别计算船体的实时颠簸位移,并对理论上可能出现的最大误差进行了分析.测量结果表明,两种模型均能有效地校正船体颠簸的影响,实测海浪波高的平均误差小于8%.

| Abstract: | A Ku-band microwave wave-height meter is proposed.It is a remote wave-height detecting equipment.It can be set up on the head of a ship to detect wave-height dynamically.In order to compensate for the ship jolt, an accelerometer is taken over the microwave detecting unit.Two mathematical models——acceleration uniform changing model and simple harmonic vibration model are proposed to compute the shift of ship moving, and the possible theoretical maximal error is discussed.The result shows that two models can compensate for the shift of ship moving effectively, the mean error of wave-height is less than 8%. |
