有量化误差的线性调频信号脉压效果分析

Pulse Compression Effect Analysis Linear Frequency──Modulated Signals ln Present of Quantization Errors

本文探讨了具有量化误差的线性调频信号脉冲压缩问题。通过计算机模拟给出了量化阶数与脉压输出主副瓣比之间的关系曲线，并根据量化误差的存在将破坏信号矩形频谱这一特性，利用逆波动法对带有量化误差的信号频谱进行修正，以便获得较高的主副瓣比。计算机模拟表明该方法是有效的。

This paper discusses pulse compression effect of linear frequency-modulated signals in the present of quantization errors,and gives the relative curve between the number of quantization and the ratio of mainlobe to sidelobe(R.M.S) by compute simulation. And accordding to the charac-ter that the quantization errors will distory the tectangular property of spectrum of signals,it has ap-plied reciprocal ripple to modifying spectrum of error signals to achieve high R.M.S. All of those methods have been approved effective by the compute simulation.
