Abstract The reflectivity performance of radar absorbing materials is usually studied through testing and simulation. Based on testing system and principle of the far-field RCS method, bow method and portable device rapid detection method, the advantages and disadvantages of the three methods were analyzed. The reflectance data of the three methods were tested and compared. The results show that the far-field RCS method and the bow method are consistent, while the portable device's rapid detection is similar to the others, but exits some differences. In the simulation study, the electromagnetic parameters measured and calculated by the free-space method were simulated and calculated by using the time domain solver or frequency domain solver of the full-wave algorithm in the simulation software (CST Microwave Studio). The simulation results show that the calculation results of the two solvers are almost identical, and they are not much different from the far-field RCS measurement results.
