Radar target recognition by high-resolution range profile based on gray system

High-resolution range profile(HRRP)of a radar target offers the distribution of scatter points along the radar line of sight(LOS).Combining the characteristic of gray relational grade models,an HRRP recognition approach based on gray systerm is proposed.Simulations results based on the HRRP dataset of five aircraft models show the effectiveness and feasibility of the proposed approach.
