扫频接收机中宽带频响自动补偿技术

在电子测量领域，扫频接收机的频率覆盖范围越来越宽，为了保证整机宽频率范围内测量信号幅度的准确性，需要对频率响应进行补偿。该文介绍了一种扫频接收机宽带频率响应的自动补偿技术，基于分段拟合的思想在FPGA内实现了扫描过程中补偿数据的自动调用、累加和补偿数据输出。实际应用表明，该文给出的设计方法合理有效，具有很高的实用价值。

Auto-compensatin Technique of Frequency Response for Frequency-swept Receiver

In the field of electronic measurement,the frequency range of frequency-swePt receiver is get- ting wider and wider,in order to ensure the veracity of measuring signal amplitude in the wide frequency range,the frequency response should be compensated.This paper introduced a kind of auto-compen- sation technique of frequency response, based on segment fitting method,the auto-loading,auto-accu-mulating,auto-outputting of compensating date can be realized during scanning process in FPGA.The practical applications show that the design method is very valid and practical.
