Design and Performance Optimization of Missile-borne Synthetic Aperture Radar Target Echo Simulation System

This paper proposes a system architecture of missile-borne SAR echo simulation based on GPU+FPGA for the problem of SAR trajectory not being accurately predicted. The real-time and distance accuracy involved in the system are demonstrated, the method of large-capacity data signal processing based on GPU and a refined delay modulation based on FPGA is proposed, and relevant simulation experiments are performed to verify the effectiveness and rationality.
