摘要
简述了基于TI公司高性能浮点DSP(TMS320C6713)的测向系统的设计情况,重点叙述了系统的核心部分———测向单元的设计方案与结构,并对DOA估计的经典方法———MUSIC算法进行了介绍,在实现过程中,采取了一些有效的措施减少了计算量,并提出实际应用中的一种简单实用的谱峰搜索方法。
The paper introduces the design of high performance DSP TMS320C6713 direction measuring system,especially describes design scheme and structure of direction measuring unit, and gives an introduction of MUSIC algorithm of DOA estimation. It adopts many measures to reduce calculation in effect. At last, puts forward a kind of brief and utility method to search wave crest during the procession of DOA searching.
