METHOD AND DEVICE FOR EVALUATING THE IMPACT OF AN ELECTROMAGNETIC ENVIRONMENT ON A RADIO RECEIVER OF A VEHICLE

摘要

The present invention relates to a method for evaluating the impact of an electromagnetic environment on a radio receiver (10) which comprises a silencer device (11) and an acoustic transmission means (16). The total signal received by an antenna (5) is transmitted to an automatic acquisition system (30). For each channel, a filtered signal emitted in said channel is extracted from said total signal, this filtered signal is transposed into a transposed signal having the same amplitude as the filtered signal, said transposed signal is transmitted to the radio receiver, it is determined state of said silencer device after receiving said transposed signal, and for each swept channel the state of said silencer device (11) is stored.
