本文比较几个抽头加权值个数较少的13位巴克码脉冲压缩旁辦抑制滤波器的性能。计算结果表明,它们的主辦下降、主瓣展宽和信噪比损失相差不大。在小的多普勒频率范围内,复杂滤波器能把最大旁瓣以及均方旁瓣抑制到较低水平,但当多普勒频率增大时,这种优势逐渐消失,並转为劣势。 This article compares the performance of several 13-bit Barker pulse compression side-by-side suppression filters with several fewer tap weights. The calculation results show that their host decline, main lobe broadening and loss of signal to noise ratio are not much different. In the small Doppler frequency range, the complex filter can suppress the maximum sidelobe and the mean square sidelobe to a low level, but when the Doppler frequency increases, this advantage disappears and turns to be inferior.
