Abstract

Abstract: A real-time bi-/multistatic synthetic aperture radar (SAR) radio frequency signal simulation method for three-dimensional scene target is proposed. This method divides scene map with 5*5m resolution and presets ackscattering-coefficient. According to the flight path and geometrical model, the key parameters such as the range between SAR and target and the weighting coefficient of the antenna pattern can be calculated. Then, the real-time simulation of bi-/multistatic SAR echo signal is realized in complex scenes by utilizing fast time-domain convolution. The validity of the method is proved by simulation.
