摘要:
针对宽带直接采样数字接收机,建立高速运动目标回波的解释表达方法,分析目标高速运动对一维距离像和逆合成孔径雷达(inverse synthetic aperture radar,ISAR)成像的影响.提出一种自适应匹配滤波的高速运动补偿方法,该方法利用雷达测距、测速系统得到的目标速度估计值构造新的匹配滤波器,补偿目标高速运动对回波信号幅度和相位的影响,从而消除一维距离像的畸变,提高ISAR成像的质量.仿真试验和实测数据处理结果验证了该方法的有效性.
Abstract:
The mathematical model of high velocity motion targets of an echo was established for a wideband direct sampling digital receiver. The effect of high velocity on range profile and inverse synthetic aperture radar (ISAR) imaging was analyzed.An adaptive matched filter method based on wideband direct sampling receiver was presented. A new matched filter was constructed by utilizing assistant low-resolution range and velocity measurement results. The amplitude and phase distortion from high velocity was compensated effectivley and the aberration impact of range profile was avoided. Therefore, the quality of high resolution ISAR imaging is improved.Simulation and experimental results show the effectiveness of the new method.
