Abstract To recognize the formation of the carrier battle group (CVBG) from passive electronic reconnaissance and location data, a shape context‐based method is proposed. The proposed method treats the location data as a graph model, and a graph matching method is used for formation recognition. The shape context and background context for each unit in CVBG is calculated and used for multi‐viewpoint shape feature, which is rotation invariance and distinctive. The experimental results show that the proposed method can recognize the formation with a higher accuracy and locate the ship with electromagnetic silence.
