摘要

多普勒滤波器组(DFB)是脉冲多普勒雷达的核心。它提供了残留杂波消除和相干积分。随着数字信号处理器(dsp)的改进，使用它们的实现变得越来越普遍。为了使DFB实时处理输入数据，通常采用多dsp并行处理的概念。本文介绍了用adsp21060实现可编程DFB的方法。通过分析在相干处理间隔(CPI)期间接收到的数据的传输速率和计算算法所需的时间，估计了实现DFB所需的总处理时间和adsp21060的数量。

An implementation and analysis of programmable Doppler filter bank using ADSP21060S

Doppler filter bank (DFB) is the heart of pulsed Doppler radars. It provides the residue clutter elimination and coherent integration. With the improvement of digital signal processors (DSPs), the implementation using them is becoming more common. Generally, for the DFB to process the input data in real time, the parallel processing concept using multiple DSPs is used. This paper presents the implementation of a programmable DFB using ADSP21060s. By analyzing the transfer rate of the data received during coherent processing interval (CPI) and formulating the time required to compute the algorithm, the total processing time and the number of ADSP21060s to implement the DFB are estimated.
