A radar imaging system based on antenna scanning is proposed.This new system can image the target without radar or target motion.In the process of antenna beam angle scanningpulse compression coding modulation is applied to the radar transmitting signalwhich is synchronized with the beam angle scanningand then pulse compression is applied to the beam scanning angle dimension to improve the angle resolution of the radar.At the same timethe wideband signal is used to improve the range dimension resolutionand the two-dimensional(range dimension and angle dimension)high-resolution radar image of the target is obtained.Simulation is carried out for different signal-to-noise ratiosthe simulation results show that the new radar imaging system is effective.
