The invention discloses a multi-sensor target characteristic simulative full-dimensional group-following type ground/water surface target system which is composed of a series of structural componentswith identity verification information, a characteristic component and a management component and is formed through joint construction of solid joint elements according to a preset scheme. The structural components are a series of body frame units; the characteristic component comprises a body characteristic simulative unit, a maneuvering characteristic simulative unit and a confronting characteristic simulative unit; the body characteristic simulative unit, the maneuvering characteristic simulative unit and the confronting characteristic simulative unit are used for simulating the multi-sensor body characteristic of a target, the maneuvering characteristics including travelling and sailing, and the confronting characteristics including smoke screen and interference; the management component comprises a control unit and a power supply unit; and the control unit and the power supply unit are used for providing control and power for the system. A standardized interface with independent identity verification information is embedded in each entity, allocation according to the demands, flexible combination, distribution control and real-time monitoring are realized, a simulative targetwith high simulation degree and economical efficiency, high constructing speed and convenient storage and transportation is provided for sensor-based weapon attack training, and a condition is createdfor constructing a wide, complicated and dynamic simulative battlefield environment.
