D.3 Conclusions
The antenna characteristics and the emitted power are key factors in the potential interference between an infrastructure radar and a vehicular radar. Given the study on the antenna, the EIRP measured and thissimulation performed using Seamcat, it appears that the probability of a vehicular radar interfering with another vehicular radar is greater than that of a scanning infrastructure radar interfering with a vehicular radar.
It is anticipated that this study shall be used to inform subsequent, more comprehensive studies so as to better understand the interference possibilities
Or:
This is an initial study intended to provide a preliminary assessment of the risk of interference.
