Strengthening of the inequality of arithmetical series
一个等差数列不等式的加强
In this thesis improved algorithms are presented as follows : ( 1 ) an algorithm based on the detection of arithmetical series is presented to deinterleave radar signals with stagger pris , especially to those with high order stagger ones . but this algorithm is limited to the model of stagger pri presented by resnick ; ( 2 ) an algorithm is presented to estimate the pris of radar signals with jittered pris based on stochastic dynamic - linear models . this algorithm fits radar signals with jittered pris well , especially when jittered amount is large
针对这种情况，本文提出了以下改进的重频分选算法： ( 1 )针对参差pri脉冲列提出一种重频分选算法，该算法使用等差数列的检测进行参差鉴别，非常适于对高参差雷达脉冲列的分选，但只局限于雷斯尼克提出的参差模型； ( 2 )针对抖动pri脉冲列提出基于动态线性模型的重频分选算法，非常适用于抖动量较大的情况。
