我们开发并演示了一种基于反尺度傅立叶变换的改进平面子阵列处理算法,该算法应用于高频冰探数据,该数据产生冰盖表面地形、冰厚和内部反射层和冰盖基岩的雷达反射率的带状测量。这是一种实时探冰成像方法。首先,对提出的算法进行了理论分析。然后给出了该算法的具体实现步骤。最后,将该算法应用于中国第29次南极科考的模拟点目标和实际数据,验证了该算法对冰盖成像的有效性。此外,与以往两种算法相比,在方位角杂波抑制能力和计算时间两个主要方面,本文算法在不影响并行计算机系统上C+MPI语言对方位角杂波抑制能力的前提下,大大缩短了成像时间,满足了测冰数据实时成像的要求。
We develop and then demonstrate a modified planar subarray processing algorithm based on the inverse scaled Fourier transform applied to very high frequency ice-sounding data that produces swath measurements of ice sheet surface topography, ice thickness, and radar reflectivity of both internal reflecting horizons and bedrock of the ice sheet. It is a real-time ice-sounding imaging method. First, theory analysis has been carried on the proposed algorithm. Then, we give the particular realizing steps to implement this algorithm. Finally, we apply this algorithm to the simulation point targets and real data collected during the 29th Chinese Antarctic Research Expedition to prove its validity of imaging of ice sheets. Furthermore, compared with two previous algorithms in two major aspects—the power of azimuth clutter reduction and calculating time—the proposed algorithm could considerably reduce the imaging time to meet the requirement of real-time imaging of ice-sounding data without degrading the ability of azimuth clutter reduction via C+MPI language on a parallel computer system.
