In this paper basic principles on digital generator of chirp waveform and four realizable schemes of hardware are described.
本文介绍了数字式线性调频波形产生器的基本原理。以及四种硬设备的实现方案。
The chirp system, which is commonly used for RCS measurement, is utilized to collect data and a method of orthogonal digital correlation mixer is suggested to process the sampled data.
该方法利用通常的线性调频RCS测量系统进行信号采集；信号处理则采用本文介绍的正交相关数字混频器。
