实孔径毫米波FMCW成像雷达系统中方位分辨力与距离分辨力不匹配,影响了成像质量。本文从分析“波束效应”的本质原因出发,提出了一种利用卷积反演—广义逆滤波法,对波束进行“伪压缩”是有效地提高成像雷达方位分辨力的方法。文中给出了对雷达实测数据作“伪压缩”处理的结果,可见处理后的方位分辨力提高约4倍。 Real-aperture millimeter wave FMCW imaging radar system does not match the azimuth resolution and range resolution, affecting the imaging quality. Based on the analysis of the nature of the “Beam Effect”, this paper presents a method of “pseudo-compressing” the beam using convolution inversion - generalized inverse filtering to effectively improve the azimuth resolution of an imaging radar. The paper gives the result of the “pseudo-compression” processing on the measured data of the radar. It can be seen that the azimuth resolving power after processing is about 4 times higher.
