摘要：
采用一维线阵天线的混合天地波雷达(hybrid skysurfacewave radar, HSSWR)系统不能利用仰角信息抑制多径扩展多普勒杂波(spread Doppler clutter, SDC),这制约了HSSWR系统在船舶目标探测方面的实际应用。针对这一问题,根据SDC与稳定海杂波在分数阶傅里叶变换(fractional Fourier transform, FRFT)域的不同聚集特性,提出一种基于FRFT的多径SDC抑制方法。理论分析和仿真实验验证了该方法的有效性。
Abstract:
The hybrid skysurfacewave radar (HSSWR) system, with 1D linear array antennas, cannot suppress multipath spread Doppler clutter (SDC), which restricts its practical application in ship targets detection. To resolve this problem,based on the difference in the concentration of SDC and stable ocean clutter in fractional Fourier transform (FRFT) field, an SDC suppression approach on the basis of FRFT is proposed. Finally, theoretical analysis and the results of simulations indicate its effectiveness.
