FPGA-Based High-Performance Real-Time Emulation of Radar System using Direct Path Compute Model

This paper proposes a Field-Programmable Gate Array (FPGA) based platform for real-time emulation of Radio Frequency (RF) signal interactions among radars and reflectors. Unlike conventional tapped-delay Finite-Impulse-Response (FIR) models, the paper presents an FPGA realization of the Direct Path Compute model for RF signal propagation. Experimental results on a Xilinx ZCU104 board demonstrate a 5-platform system of the emulation range of 2.78km to 27.3km at 180 MHz bandwidth.
