摘要
直达波相对目标回波具有很强的能量,使其对穿墙探测雷达(TWDR)的目标回波信号检测造成了严重干扰。可根据各个测点直达波的强相关性,基于SVD分解提取参考直达波,采用自适应对消算法抑制直达波。通过对实测数据的处理结果看出,此方法有效地抑制了直达波,将回波的信干比(SIR)由-20.402 dB提高到20.479 dB。
The direct wave, because of its great energy, has great effect to the detection of the target echo of the TWDRo In terms of the strongly correlation of the direct wave and based on the SVD decomposition to distill the referenced direct wave, we applied the adaptive interference canceling＇ method to remove the direct wave. From the result after disposing, this method can remove the direct wave and increases Singal to Interference Ratio（SIR） effectively.
