Recently, shipborne radars are being developed into fully-digital Active Electronically Scanned Array (AESA) multifunctional radars (MFR) that are capable of electronic beam steering, simultaneously detecting and tracking multiple targets in a complex maritime environment, and performing electronic countermeasure functions in real-time. However, because the development process of a radar is expensive owing to its high complexity, using Simulated Signal Generator (SSG) that can emulate the function of an antenna proves effective in radar development. In this study, we propose a real-time implementation method for SSG capable of simulating maritime battlefield environments and targets using fully digital-based antenna simulation. We propose a CPUand FPGA-based real-time system architecture, fixed-point operation, real-time channel noise generation method, and real-time beamforming structure to generate modeling results that are presented.
