摘　　要：宽带一维成像系统的关键技术是超大时宽带宽积信号的数字脉压。为了在有限的硬件资源上实现超大时宽带宽积信号的数字脉压，本文提出了一种采用提高FPGA处理时钟，降低数据率，有效使用乒乓操作及合理利用串行处理和并行处理等处理手段的设计方法，该方法不仅降低了设计成本，更重要的是，它解决了两个或多个处理器在时钟上不能完全同步的问题。The key technology of one-dimension imaging system lies in digital pulse compression（DPC） of super time duration-bandwidth product signal. This paper provides a design method to implement the DPC of super time duration-bandwidth product signal on limited hard resources. This method uses such approaches as improving processing frequency of FPGA, reducing data-inputing frequency, effectively using ping-pong operation and reasonably using serial processing and parallel processing. The method not only can reduce the cost of design, but also can resolve the problem that two or more processors can not synchronized on clock.
