利用发生破碎的海洋回波多普勒谱的幅度和中心频率显著增强的特点,通过设置阈值门限的方法检测发生波浪破碎的距离元,得到雷达探测海域中破碎波发生的位置.并对被破碎干扰的数据进行经验模式分解处理,消除破碎波造成的影响.实测数据处理结果表明:破碎波检测结果和实际情况一致,对发生破碎的距离元数据处理后减小了多普勒谱中心频率的偏差,提高了反演结果的准确性,进而验证了此算法的有效性.
Based on the characteristic that the amplitude and center frequency of the Doppler spectrum of the crushed oceanic waves are significantly enhanced, the distance element of the wave crushing is detected by setting the threshold threshold, and the position of the crushing wave in the radar detecting sea area is obtained. Of the data processing model decomposition to eliminate the impact caused by the broken wave.The measured data processing results show that: the broken wave detection results and the actual situation, the occurrence of crushing distance metadata processing reduces the Doppler spectrum center frequency deviation , Improve the accuracy of the inversion results, and then verify the effectiveness of this algorithm.
