海面回波 meaning in Chinese
sea clutter
sea echo
sea return
Examples
- Progress , though steady , has been slowly , due largely to difficulties inherent in attempts to characterize a random natural phenomenon in terms of a limited set of parameters . for many years , various non - gaussian probability distributions have been offered as models for the amplitude of sea clutter
对海杂波的研究迄今已有50多年，但其实验数据和理论远不能令人满意，还不可能对海面回波的电平(作为雷达参数和海面状态参数的函数)做出高度准确的预测。 - Combine with the project " hf ground wave radar supervise sea status " of state 863 project , retrieving wind direction from hf radar doppler spectrum and the showing of wind field , current field , wave field are researched in this paper . the problem of how to represent the sea surface parameters by computer is concerned , too
本文结合863 - 818 - 01 - 02课题“高频地波雷达海洋环境监测技术” ，研究了由高频雷达海面回波提取风向信息和海面风场、浪场、流场信息的计算机表征方法及其数据传输反演和表征的若干问题。 - A new if simulation signal digital model was developed , which has the ability to simulate the ocean return wave noise and the instrument thermal noise . by this simulation data , smle is successfully tested , and the rf ocean return wave simulator also worked correctly . it is difficult for altimeter to realize closed loop internal calibration with a large time - bandwidth product
( 4 )提出了雷达高度计海面回波中频仿真信号的数字模型，该模型具有仿真高度计海面回波噪声和仪器热噪声的功能；基于该模型的软件仿真器成功的对高度计跟踪器进行了验证；同时，该模型仿真的信号应用于雷达高度计射频回波模拟器也获得了成功。
