technical field

The invention relates to the fields of electromagnetic waves and sound waves, in particular to an array scanning transmitter and receiver based on a three-axis gyroscope structure.

Background technique

Existing array scanning transmitters and receivers are based on linear arrays, curved arrays, plane arrays, curved arrays, spherical arrays, etc. When the transmitter transmits fixed-phase signals, if the array does not move, the transmitting azimuth is fixed at a fixed phase.
