短波宽带阵列信号源的设计与实现

Design and realization of HF wideband array signals generator

为了在实验室给宽带阵列信号处理设备的研制、维护提供一个较好的仿真环境,介绍了一种基于多片DSP芯片ADSP-TS201S和数字上变频器AD9857构成的宽带阵列信号源,模拟实现了最大带宽为4MHz的短波宽带阵列信号。主要包括系统设计方案、系统硬件设计和DSP软件设计等。

To provide a better simulation environment for array signal processor manufacture and maintenance in the laboratory, this paper presents a design of HF wideband array signals generator based on multiple DSP ADSP-TS201S and digital upconverter AD9857. The generator simulates the generation of HF wideband array signals with maximum frequency of 4 MHz. The system scheme,the hardware design and software of DSP are described.
