Abstract
Digital beam forming (DBF) is the main computation in digital signal processors for radar and sonar systems. Conventional DBF is made up of multipliers and adders, but it cannot satisfy the need of real time processing because of its slow speed. In this paper, the authors introduce the distributed arithmetic (DA) algorithm for DBF. They find that the DBF circuit, according to the DA algorithm, is easy to realize in LSI with high speed and effective hardware. DBF chip has been designed using 3 mu m CMOS technology. The chip contains only 1000 gates and its data channels are changeable.<>
数字波束形成(DBF)是雷达和声纳系统中数字信号处理器的主要计算部分。传统DBF由乘法器和加法器组成，但速度慢，不能满足实时处理的需要。本文介绍了DBF的分布式算法(DA)。他们发现，根据数据分析算法，DBF电路易于在大规模集成电路中实现，具有高速和有效的硬件。DBF芯片采用3 μ m CMOS技术设计。该芯片仅包含1000个门，其数据通道是可变的
