Design of the Simulation and Assessment Software of Missile-Borne SAR Imaging System

It is a key step to study and design the missile-borne SAR (Synthetic Aperture Radar) by the computer simulation. In this paper, we present a simulation and assessment software of the missile-borne SAR imaging system, which calculates the flight path of the missile, generates the echo data of the target, outputs the imaging result and its quality assessment. After dividing functional modules, we exhibit each function of the modules respectively. Moreover, three important problems are analyzed: the computation load of the echo data generation, the approach to generating layover and shadow of the 3D target, and the imaging algorithm and geometric correction formula. The simulation example shows the feasibility and effectiveness of the proposed software.
