Method and device for calculating shielding rate of satellite communication antenna of helicopter and electronic equipment

The invention provides a method and device for calculating the shielding rate of a satellite communication antenna of a helicopter and electronic equipment, and relates to the technical field of satellite communication. Comprising the following steps: acquiring a rotor contour line of a helicopter under a rotor surface coordinate system at the current moment, an antenna shielding component contour line and a first beam vector pointing to a satellite from a helicopter satellite communication antenna under a helicopter instantaneous navigation coordinate system; determining a first rotation matrix from an antenna surface coordinate system to a helicopter instantaneous navigation coordinate system based on the first beam vector; determining projection contour lines of the satellite communication antenna and the antenna shielding component in a rotor plane based on the first beam vector and the first rotation matrix; and calculating the satellite communication antenna shielding rate of the helicopter based on the
