摘要
目前解决合成孔径雷达盲区问题的方法通常是采用可变脉冲重复频率来实现 ,然而其变化的PRF会导致非均匀采样 ,增大了后续成像处理的运算复杂度。文中从脉冲波形的角度提出一种解决盲区问题的新方法 ,并阐述了该方法的原理 ,最后用仿真结果证实了其正确性。
The blind zone problem in the wide-swath synt he tic aperture radar (SAR) is usually solved by method of variable pulse repetiti on frequency (PRF). It is well known that this method causes nonuniform sampling , which makes the image processing more complex. In this paper, a new method is proposed to solve the blind zone problem by using special shape of pulse. The pr inciple of this new method is presented in this paper and the simulation results are given, which demonstrate the validity of the proposed method.
