相控阵多普勒计程仪八通道海底回波信号模拟器设计

摘要

Based on Doppler principle, this paper describes the hardware and software design based on phased array sea echo simulator. According to actual demands, the design of the echo simulator software consists of wave-form generator, D/A controller and the DSP/BIOS configuration block. Finally, the paper validates the simulator under different conditions of signal waveform, to ensure that the signal simulator meets the design.%本文从多普勒原理出发，简述了基于相控阵海底回波模拟器的软硬件设计思路。根据实际需求将回波模拟器的软件划分为波形生成器、D/A控制器和DSP/BIOS配置三个部分进行分块设计。最后对不同条件的信号波形进行验证，确保信号模拟器满足设计要求。
