Modelling and simulation of a stepped frequency radar system based on LabVIEW

In the radar system, modelling and simulation can guarantee the high reliability and correctness of system design, shorten designing period and reduce development cost. This paper discusses signal processing system of the SFR (stepped-frequency radar), especially the several key processing steps to get the HRRP (high resolution rang profile). The system simulation has done based on LabVIEW (Laboratory Virtual Instrument Engineering Workbench) platform, estimates the range and velocity of the target, and gets the real HRRP, The results validate the feasibility and correctness of the system.
