| 摘 要： | 针对多普勒频移带来脉压失配问题,为克服现有算法运算量大且占用大量存储空间的弊端,文中提出一种快速消除多普勒频移对数字脉压(DPC)影响的算法。该算法基于傅里叶变换性质,利用单向循环链表技术,对无多普勒频率时的匹配滤波系数表重新选址。仿真结果表明,新算法在大多普勒频移时信噪比损失小,且不会增加运算量和存储空间,具有很高的应用价值。

| Abstract: | For the problem of mismatch of pulse compression due to Doppler frequency,a novel fast algorithm of eliminating the effect on Doppler frequency shift on DPC is proposed in this paper.In the algorithm,matched filter coefficients are adaptively generated by addressing in the circulatory linked list consisting of Doppler-free frequency coefficients.Simulation indicates that the SNR-losing with high Doppler frequency can be decreased by this algorithm without additional computing costs and memory space.So this ... |
