Child target object for in-vehicle living body detection

The invention provides a child target object for in-vehicle living body detection, the child target object has the same visual features as a real child under a visual sensor, and the visual features comprise the child appearance and breathing fluctuation. Under the millimeter-wave radar, the millimeter-wave radar has radar reflection characteristics the same as those of a real child. Reflection features include RCS and micro-Doppler effects generated by breathing and heartbeat. Under the pressure sensor, the degree of freedom of the child has the same weight and pressure as that of a real child. The child freedom degree has enough freedom degrees, the motion characteristics of a real child in a vehicle cabin can be simulated, body detail parts (such as the head, the arms and the legs) restore the characteristics of 0-6-year-old children in China under a visual sensor at the ratio of 1: 1, and the child freedom degree neck has two freedom degrees of rotation and pitching; the shoulder joint and the hip joint h
