Comparison of the total number of the radar astronomy transmissions
with respect to that used for sending messages to extra-terrestrial
civilizations reveals that the probability of detection of the radio signals to
extraterrestrials (ETs) is one million times smaller than that of the radar
signals used to study planets and asteroids in the Solar System.
