Abstract :
For high-frequency radar, ship targets detection is seriously affected by the strong sea clutter. To solve the problem, a design of multi-frequency radar receiver system is presented, which completes digital mixer and digital down converter for multi- channel digital receivers based on FPGA and carries out system controls and data transmission by USB2.0 interface. The system closed-loop test shows that the scheme can work in multi-frequency mode which meets the requirements of HF radar application.
