摘要
Abstract
In order to solve the problems of complex, high cost, and difficult debugging of K band wideband linear correction device, a VCO open loop linear correction method based on FPGA is proposed. With VCO tuning characteristics of the open loop linear correction principle, we can make open loop broadband linear correction for the VCO tuning characteristics on the basis of the D/A chip controlled by FPGA. At the same time, the clock generated by controlling FPGA can generate arbitrary wide linear frequency modulation continuous wave and carry out experiments. Experiment results show that, when bandwidth is 400 MHz, the nonlinear is less than 0.1%, the open loop linear correction method is simple, low cost and satisfies the system index requirements.关键词
