无盲区数字信道化频谱检测方法

Digital Channelization Technique Without Blind Zone

传统数字信道化模型存在信道间盲区和混叠,难以满足现代非合作接收机中全概率检测的任务要求,本文提出一种通带重叠的数字信道化高效模型,在频域对各通道输出信号进行了无缝"拼接",解决了跨信道信号的全概率检测问题。本文对提出的算法进行了原理仿真,利用测试数据对定点化后的算法性能验证,测试结果表明高效算法模型可以应用于非合作宽带信号无盲区、全概率检测的场合。

Since blind zones and overlaps exist in the traditional digital channelization model,it is hard to meet the requirements of total probability detection in modern electronic reconnaissance receiver.This paper proposes a overlapping digital channelization model.The processed signals are joint together seamlessly in the frequency domain,and the detection of cross channelization signals becomes possible.The proposed algorithm is simulated and tested by real data.The results demonstrate that the proposed algorithm is high efficient,and can be applied to the place of total probability detection for non-cooperation signal receiving.
