Research on imaging simulation of airborne fire control radar for simulated training

A uniform simulation method was presented to realize ground imaging of RBM, DBS and Spotlight SAR for simulated training. The three imaging modes are widely used by modern airborne fire control radars. Considering the requirement of training real-time and the simulated images used for pilots observation, this method computed RCS images of ground based on the facet model and fused the radar image features, such as shadows, layovers and speckles, to get simulated images directly. The problem of dynamic image display in GL Studio was solved at the same time. Specially, the reality and real-time of this simulation method was evaluated qualitatively and quantitatively. Experimental and probational results show that the radar simulated images obtained by the proposed method are competent for the simulated training in army.
