摘要
分析了脉压的基本原理。在FPGA平台上,设计了可以实现从16点到4096点可配置的通用脉压系统。采用基-2双蝶形、乒乓RAM和流水线的处理模式,大幅度地提高了系统的处理性能。通过改进地址产生、浮点加法提高了系统的处理速度。最后提出一种低成本的测试平台以大大降低测试成本。系统可以稳定工作在150M下,处理4k点的时间是170μs,处理精度达到-86dB。
The basic principles of pulse compression are analyzed,A configurable general pulse compression system from 16 points to 4 096 points is designed,The ping-pong RAM memory and pipelining of the processing hardware framework are designed double-butterfly.The system's processing performance is improved. The traditional design of floating-point addition and address generator are improved.A low-coast test platform for high-speed logic circuits is designed. Results show that a complex 4 k point pulse compression is calculated about 170 μs at 150 MHz,the processing precision is-86 dB.
