Abstract针对步进频率表面穿透雷达(SFGPR)得到的目标图像的分辨率和穿透深度被系统噪声和地下媒质损耗所限制这一问题,提出了应用多重信号分类(MUSIC)算法对SFGPR信号进行处理以得到目标深度信息.在实验中,采用单极化指数模型对SFGPR接收信号进行仿真,并考虑系统噪声和媒质损耗的影响,将MUSIC算法得到的目标图像与传统的快速傅立叶变换法(FFT)得到的目标图像进行了对比.仿真实验结果表明,在低功率噪声和低损耗媒质情况下,MUSIC算法比FTT算法可以提供更高的距离向分辨率和回波幅度.
Other AbstractIn view of the p roblem that the resolution and penetrating dep th of the SFGPR target images are limited by the system noise and underground medium loss, theMUSIC is p roposed for signal p rocessing of SFGPR to get the dep th information of the targets. In experiment, the single polarization exponentmodel is used to simulate the SFGPR receiving signal, the influence of system noise and medium loss is considered, theMUSIC images are compared with the conventional FFT images. Simulation results show thatMUSIC has both higher dep th resolution and higher receiving signal level than FFT in weak noise background and low lossmedium.
