What is the maximum radar cross section (square meters) of an automobile license plate that is 12 inches wide by 6 inches high, at a frequency of 10.525 GHz (the fre- quency of an X-band speed radar)? b. How many degrees in the vertical plane should the plate be tilted in order to reduce its cross section by 10 dB? WebBased on the above aspects, the developed CP model is validated through the RCS evaluation of an infinite circular PEC cylinder with a radius of λ / 2. To this aim, Figure 4 shows the entire computational domain, where the excitation is a TE plane wave with λ = 1 m and an incident angle of θ inc = 0 °.
