摘要
Abstract
The analog source holds an important position in the test and calibration system of radio radar equipment.The beacon machine equipped with a certain type of Doppler radar has defects such as being bulky and heavy,and being unable to simulate Doppler signals,making it difficult to meet complex test requirements.Therefore,a small dynamic analog source based on the implementation of FPGA is designed.This analog source,through the collaborative operation of FPGA and digital DAC,achieves rapid frequency adjustment,en-abling the carrier signal to superimpose Doppler information.In addition,the signal frequency and amplitude control methods of the ana-log source are flexible control methods,allowing for both wireless real-time adjustments and output according to pre-stored data.It can not only be adjusted wirelessly and in real-time but also output according to pre-stored data.This effectively compensates for the defi-ciencies of the original beacon machine and provides strong support for the test and calibration of radar equipment.关键词
