Design of High Speed Ethernet Based Receiver Processor Unit for Radar applications

Receiver processor of the Radar system is main part for detecting and analyzing the received signal paramters in the presence of clutter. One of the functions of the receiver processor is to accept commands in the form of messages and process for different receiver applications. These commands are initiated by the system controller to receiver processor as per the system requirements. In this paper, the receiver processor is designed for Electronic Warfare application based on high end FPGA.The communication takes place between system controller and receiver processor in the FPGA through high speed Ethernet link.For processing these commands, embedded application software is developed using C language.A Graphical user interface is also developed in LabVIEW for giving command inputs to the receiver processor. The developed firmwareis able to transmit a high amount of data sufficiently to select filter bank, threshold level and quadrature position based on the input commands.The commands have been successfully executed and results are observed on the FPGA output pins.
