高分辨率线性调频信号产生及预失真补偿

Generation and pre-distortion compensation of high-resolution LFM signals

提出了用于高分辨率合成孔径雷达的线性调频信号产生的方案,产生的信号时宽带宽可在数字电路中灵活可变。同时实现系统的幅相预失真误差补偿,并给出大时带宽信号研究结果,相关技术已在一些工程中应用,获得满意结果。

In the paper,the method of generating of wideband LFM signals is presented, and the pre distortion compensation is described. The related technique has been applied in some projects and achieves favourable results.
