Self-adaption Doppler frequency offset resisting time modulation array antenna system

The invention discloses a self-adaption Doppler frequency offset resisting time modulation array antenna system which comprises an antenna array subsystem, a radio frequency switch network subsystem and a field programmable gate array (FPGA) control subsystem. The antenna array module is formed by four pairs of identical printing dipole subunits (1) which are in serial feed. The radio frequency switch network module is composed of four one-bit phase shifters (2) and a one-in-four power divider combiner (3). A speed collection unit (11) composed of a uniaxial accelerometer and an integrator is integrated on an FPGA control plate (9) of the FPGA control subsystem to acquire relative speed information of the current environment. Control sequences of switches on the corresponding phase shifter (2) can be calculated through the information, and work states of the phase shifters can e changed by controlling a signal transmission line (8). The system has the Doppler frequency offset compensation function, has the self-adaption advantage, can control a beam to point at an appointed communication target and is applied to the fields of high speed railway communication and the like.
