摘要
针对ＰＲＩ的调幅度较大或ＰＲＩ较长的脉冲信号，普通平面变换法显得不直观，难以分辨出特征曲线．对此作者提出了一种将调幅度变小，将ＰＲＩ变短的方法，即将待分选信号进行压缩平面变换后，使特征曲线变得明显而易于分选。
The plane transformation technique (PTT) can separate concentrated signals fast, effectively and intuituvely. However, it is difficult and no longer intuitive for an ordinary PTT to separate the pulse signals with long pulse repeat interval (PRI) and large amplitude modulation. In this paper, the compression plane transform technique is presented, which makes the characteristic curves more clear and easy to separate by compresing PRI. The method presented makes the PTT more perfect and practical.
