MIMD声纳自身干扰对消系统

MIMD Sonar Self interference Cancelling System

在分析了声纳信号并行处理的几种形式后，结合自适应格型算法阶递归的特点，采用多片数字信号处理器（ＴＭＳ３２０Ｃ２５）设计了一个ＭＩＭＤ并行处理器系统。应用该系统实现了Ｇｉｖｅｎｓ格型算法，进行了声纳自身干扰对消实验。

After the different forms of Sonar signal parallel processing are analysed,a Multiple Instructions Multiple Data (MIMD) Sonar self interference cancelling system which consists of multiple processing chips (TMS320C25) is developed in accordance with the order recurrence feature of the adaptive lattice algorithm.A Givens Lattice Algorithm (GLA) is realised on the proposed system.The expriment shows that the cancelling system reaches a high calculation efficiency and has a steady performance.
