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。
In this paper basic principles on digital generator of chirp waveform and four realizable schemes of hardware are described.
波形产生器主要由dsp和数字上变频器构成，DS P作为主控制器设定数字上变频器的调制方式和输出波形。
The waveform generator is composed by DSP and quadrature digital upconverter (QDU). DSP is used as main controller to decide the modulation mode and output waveform of QDU.
