MIMO RADAR SYSTEM AND PHASE SYNCHRONIZATION METHOD THEREFOR AT DYNAMIC TARGET END

摘要

The present invention relates to the technical field of radars, in particular to an MIMO radar system and a phase synchronization method therefor at a dynamic target end. In the present invention, two time slots are used as one cycle to estimate frequency and phase parameters of a signal, and the estimated parameters are utilized to construct new frequency and phase parameters, and ideal phase synchronization at a dynamic target end is realized by means of a radar feedback array transmitting a feedback signal. Compared with the existing source end and receiving end phase synchronization techniques, the number of required time slots is greatly reduced when the number of radars is relatively large; in addition, the requirements of the proposed phase synchronization techniques for a network topology structure of a radar system are not high, and multiple iterations are not required to reach the effect of state convergence, thereby improving a convergence speed, greatly reducing the power consumption of a network, and prolonging the service life of the network.
