description The utility model discloses a tracking system based on a wave beam scanning antenna. The system includes the antenna, a phase shift network, a low-noise amplification unit, a receiver, a frequency mixer, a frequency source, an A/D sampler, a motor driver, an azimuth motor and a main control unit. An electromagnetic output end of the antenna is sequentially connected with the phase-shift network, the low-noise amplifier, the receiver, the frequency mixer, the A/D sampler, the main control unit and the motor driver. A control signal output end of the motor driver is connected with a signal input end of the azimuth motor. A reference frequency input end of the frequency mixer is connected with an output end of the frequency source. The antenna is connected with the azimuth motor. The tracking system drives the azimuth motor to rotate when an error angle exists so as to enable the antenna to rotate and thus a tracking error angle is 0 and the sensitivity of the system is improved; and at the same time, it can be prevented that the azimuth motor rotates continuously and thus the power consumption of the system is reduced.
