摘要
本文讨论用最小二乘法处理VVP技术下测得的多卜勒速度来获取矢量风场信息量的方法。 从实际考虑,详细描述了近于真实的降水回波信号的模拟过程,着重分析了此模拟信号的估计结果及其误差,并就该方法探测的最佳范围进行探讨。最后简单分析非线性场的结果。
In this paper, the method of the retrieval of vector wind field measurements with a least-square procedure through processing the Doppler velocity data obtained by VVP technique is discussed. The parameters of wind field and their errors due to white noise, Doppler spectrum width and nonlinearities in the wind field are estimated by using simulated data similar to true one, and then the optimum detection range for VVP technique is determined.
