Design of a low-cost airborne radar target simulator based on FPGA

In this paper, we present a low-cost airborne radar target simulator based on FPGA, which consists of three parts: control and video processing module, intermediate frequency (IF) processing module and radio frequency (RF) processing module. The system is capable of simulating target echoes with range, Doppler, direction and the other information in real time. We also elaborate the highlights of design methodology and implementation from theory to practice. The results show that using FPGA technique make The simulator based on FPGA makes the system´s reliability and stability are enhanced with low-cost.
