【摘要】 该文提出了一种新的合成孔径雷达(SAR)运动目标检测和成像方法,即利用短时FFT处理原始数据,在距离多普勒域对运动目标进行识别和参数检测,获得的目标参数可以用来正确成像运动目标。对运动目标回波特点和雷达参数的分析证明了这一方法的可行性和有效性。最后通过对包含真实运动目标回波的原始数据进行处理, 对该方法进行了验证。更多还原

【Abstract】 This paper presents a new method for moving target detection using SAR. With the help of short FFT analyses and CFAR detection, this method calculates the moving parameter of the target from range migration effect. An analysis on the detection precision and range of target speed is given in the following characters. The advantage and the limit of this method are indicated and the detection results from real data demonstrate the accuracy of the conclusion.更多还原
