Embodiment Construction
[0027] The present invention will be further described below in conjunction with the accompanying drawings.
[0028] A motion posture perception method based on the stationary characteristics of electromagnetic wave polarization three-dimensional electric / magnetic signals, such as figure 1 , 2 shown, including the following steps:
[0029] Step 1, according to the movement situation of the moving platform, define the reference attitude coordinate system of the moving platform, the coordinate system where the real-time attitude antenna of the platform moves is defined as the real-time attitude coordinate system, and determine the conversion relationship between the moving platform reference attitude coordinate system and the earth coordinate system;
[0030] Step 2: At the reference attitude of the motion platform, three orthogonal electric / magnetic field sensors in the polarization-sensitive electromagnetic vector sensor receive electromagnetic wave signals, and estimate the ...
