摘    要:给出了一种在脉冲压缩技术中实现低的压缩脉冲距离旁瓣的方法,由希望的压缩脉冲波形来设计加权滤波器。导出了可实现低的压缩脉冲距离旁瓣的条件。实验用声表面波(SAW)器件实现时,对线性调频信号,其压缩脉冲最大主旁瓣比为50dB。而用数字方法实现时,压缩脉冲最大旁瓣电平还受A/D及D/A变换器位数的限制。

关 键 词:脉冲压缩  信号处理  旁瓣抑制  目标探测

Abstract:In this paper, a method used in pulse compression technology for side-lobe suppression of pulse compression is presented. In the method, the parameter of filter is obtained by the desired wave of compression pulse and the qualification for side-lobe suppression of pulse compression signal is educed. An experiment using SAW dispersive delay line is done for linear frequency model signal. It shows that the theoretical value (-50dB side-lobe levels) is in accordance with the experimental one. Another experiment using digital technique demonstrates that the side-lobe of pulse compression signal is restricted by the figure of A/D and D/A convertor.
Keywords:Pulse compression Signal processing Sideband suppression Target detection
