Integrated radar signal processing using FPGA dynamic reconfiguration

With the development of radar signal processing, integration of radar communication and guidance design on the hardware becomes popular. Dynamic partial reconfiguration of FPGA can reconfigure part of its logic resource at run time. In this article, an integrated radar signal processing hardware platform was designed, on which both LFM waveform and FSK waveform were processed with method of FPGA dynamic partial reconfiguration. FPGA receives the partial reconfiguration file transferred from host computer and reconfigures part of its logic changing the function. FPGA can be time-multiplexed by using FPGA dynamic partial reconfiguration which can reduce resource usage and power dissipation.
