Abstract:

The paper based on FMCW radar system model,the first use Matlab to triangular wave modulation simulation,and were in perfect condition and the effect of noise and phase error on the signal processing of the triangular wave modulation FMCW radar system simulation.The simulation results illustrate the impact of noise and phase error on the system,and analyzes the main factors affecting the results of the simulation process,and ultimately summed up the advantages and disadvantages of FMCW system,which provides a point of reference for the deepening of the specific application of FMCW radar.

Key words: FMCW radar;triangular wave modulation;Matlab simulation
