| 摘要: |
| 电子情报数字化侦察接收机中，Δt直方图去交错方法在脉冲串数量较多和脉冲
间隔抖动较大的复杂电磁环境下，不能得到满足数字化自动峰值处理的高度比。在分析一定
纯净比下，以脉冲字参数向量相似性测度对间隔区间记数加权，建立加权复数直方图，对接
收脉冲串进行去交错处理。经过仿真计算，加权复数直方图相比经典方法能明显提高去交错
效果，更易于数字化自动峰值处理。 |

| Abstract: |
| In electronic intelligence digitized reconnaissance receiver, Δt h
istogram deinterleaving algorithm cannot get ample height ratio to automatic pro
cessing digitized peak value in complex electromagnetic environment when there a
re a great quantity of pulses and high interval dither. Under a set pure ratio,
weighted complex histogram is built with similarity measure of pulse word parame
ter
s vector to process deinterleaving of received pulse train. Computer sim
ulation shows that weighted complex histogram can get better deinterleaving eff
ect than cl
assic method, and it is more easy for automatic processing peak value. |
