摘要:

基于PRI分选有多种方法,其中PRI变换法对脉冲重复间隔有较高的估计精度,并克服了传统直方图统计法中的子谐波问题。文中在对PRI变换法进行深入研究的基础上,提出了一种改进的自适应PRI变换法,仿真结果验证了新算法的可靠性。

Abstract:

De-interleaving of radar signal is a key technology in the field of electronic countermeasures,and the pulse repetition interval of radar signal is an important sorting parameter.Up to now,several methods based on PRI parameter have been brought forward.PRI transform algorithm can estimate the PRI parameter precisely,and the method overcomes the subharmonic problem produced in the histogram method.After the intensive study of the PRI transform algorithm,An improved self-adaptive method based on it is advanced in the paper.

Key words: radar signal sorting;PRI transform algorithm;self-adaption
