摘要
为了满足舰船导航雷达回波信号的信噪比,提升雷达回波信号采集的深度与广度,提出FPGA的舰船导航雷达回波信号采集设计。采用FPGA采集控制硬件,设计FPGA计算控制的雷达回波信号采集平台。通过在平台系统内引入FPGA雷达回波信号采集逻辑,完成对信号采集深度与广度的量化计算。最后,通过仿真测试的方式设计一组实验,对提出的FPGA的舰船导航雷达回波信号采集设计进行可行性验证,证明设计的雷达回波信号采集灵敏度高、范围广、距离远、精度高的优点。
In order to meet the signal-to-noise ratio of the ship navigation radar echo signal,the depth and breadth of the radar echo signal acquisition are improved,and the design of the ship navigation radar echo signal acquisition based on the FPGA is proposed.The radar echo signal acquisition platform controlled by FPGA is designed by using FPGA acquisition and control hardware,and the quantitative calculation of signal acquisition depth and breadth is completed by introducing FPGA radar echo signal acquisition logic into the platform system.Finally,a set of experiments are designed by means of simulation test,and the feasibility of the proposed FPGA radar echo signal acquisition design for ship navigation is verified by experiments.It is proved that the design has the advantages of high sensitivity,wide range,long distance and high accuracy.
