获取舰船波浪参数对于舰船的航行安全和武器使用十分重要。针对舰员缺乏有效手段实时获取舰船当前航行局部海域的波浪信息的问题，提出利用船载北斗接收机输出的天线高度信息反演波浪场信息的新方法。该方法认为北斗测量天线相对海平面高度的信息变化，反映了波浪的运动状态，通过对天线高度信息进行谱分析，根据波浪频谱特征，进行带通滤波，从而在频域提取出波浪信息，经过傅里叶反变换后，得到时域波浪信息，然后计算波高和波周期。海上实船试验结果表明，与浮标测量的准确波浪参数相比，通过该方法测量得到的SWH波高误差小于6%，波周期误差小于10%。
It's very important to get wave parameters information for vessels' safety. But lack of vessels mounted equipments to measure wave parameters in real time and real spot make it difficult for crews. One new method is presented to solve the problem by dealing with vessel mounted compass navigator's output data. This method deems that the change of altitude of antenna reflects the wave movements above mean sea level. First, to make a spectrum analysis of antenna altitude data, second, to design a band-pass filter according to the wave frequency-spectrum character to extract the signal in frequency-domain, third, to extract the data in time-domain via inverse Fourier transformation, at last, the wave parameters such as SWH and period can be resolved. The test results on a ship shows the methods is feasible, its SWH determination accuracy is better than 6%, and the period determination accuracy is better than 10%.
